Cryogenic Valves

DescriptionPHPK Valves have been engineered, designed, and manufactured using the latest state-of-the-art technology. All pipe size valves have been fully computer analyzed and tested for a 600 psig, non-shock, WOG rating.

1

Unique design and manufacturing techniques enable PHPK to offer a variety of valve end connectionsincluding flanged, threaded, socket weld, and true buttweld (important for oxygen cleaning). In addition, the PHPK valve has no hidden cavities or crevices which can trap contaminates and cannotbe cleaned by normal cleaning techniques. PHPK valves are designed with a fabrication controlledgas path (.003” to .004”) allowing the use of simple warm O-ring bonnet seals which enable the valvesto be operated in a totally inverted position with cryogen flowing through the valve. Manual valve (PV-60, PV-90) stem seals are engineered to allow replacement without total system shut-down orremoval of the cryogen from the line. The valve seat seals are installed using a locking design (patentpending) which eliminates potential seat leakage from improperly installed seals or leakage pathsopen to the process stream. The use of state-of-the-art PHPK-specified, patented oxygen compatibleplating techniques eliminates galling of critical components.

All PHPK pipe-size valves are completely interchangeable between manual, remote (on/off), checkvalve, and remote flow control, without changing the valve body. All seals on vacuum jacketed valvescan be replaced without disturbing the vacuum. Flow arrows and identification tags are cast into thevalve bonnets 1/2” through 2” NPS to avoid confusion when the valves are vacuum jacketed.

PHPK Pipe Size Valve Ordering SpecificationAll cryogenic extended-stem globe valves will be PHPK model PV-60, PV-70, PV-80, PV-90 or CV series. All valvecomponents will be totally interchangeable between valve models and flow characteristics without replacing valvebodies. Castings will be lost wax investment cast, ASTM A-743, grade CF3 (304L) stainless steel, 100% radiographand zyglo inspected. Valve component materials of construction will be 304L or 300-series stainless steel. Bonnetswill be bronze alloy. Valve bonnets will have permanently cast or marked flow arrows when vacuum jacketed.All butt weld connections will be “true butt weld“ with no closed-end cavities (such as socket welds which cannot be easily cleaned for oxygen service). Weld connection between body extension tube and valve body castingwill be a butt weld connection. Seal disk material will be Neoflon PCTFE M-400H (formerly Kel-F). Valve barreland bonnet bolts will be plated with a PHPK-specified, patented nickel/teflon plating, which has been tested andapproved for oxygen service. This plating, unlike chrome, does not chip or flake and provides a homogeneoussurface to prevent galling. The valve design will provide a close-tolerance fit (appoximately 0.003”) between thebarrel and the body extension tube, allowing operation in any orientation, even upside down, while ensuring bon-net (Viton, fluorocarbon rubber, O-ring) seals remain warm when the valve is in cryogenic service. Stem packingwill utilize dual Viton O-rings on the static and dynamic areas of the sealing surfaces. Bonnet seal will be a singleViton O-ring. Valves will have self-locking seat seals which do not require staking or welding for assembly ormaintenance. All vacuum jacketed valves will be serviceable without breaking vacuums. Stem packing in manualvalves (PV-60, PV-90) will be replaceable without removing the valves from service.

PHPK Cryogenic Globe Valves

The flow characteristic of a control valve is considered to be the relationship between the flow rate through the valve and the valve travel as the travel is varied from 0 to 100%. “Inherent flowcharacteristic” refers to the characteristic observed with a constant pressure drop across the valve.The “installed flow characteristic” is obtained in service where the pressure drop varies with flowand other changes in the system.

The purpose of characterizing control valves is to provide for a relatively uniform control loop stability over the expected range of the system operating conditions. To establish the flow characteristic needed to “match” a given system requires a dynamic analysis of the control loop.Analysis of the more common processes have been performed to establish some useful guidelinesfor the selection of the proper flow characteristic. The following is a look at the flow characteristicsin use today:

Discussion of Flow CharacteristicsThe accompanying graph illustrates typical flowcharacteristic curves. The quick opening flowcharacteristic provides for maximum change inflow rate with minimal stem travel, while maintaining a fairly linear relationship.

Additional increases in valve travel give sharply reduced changes in flow rate, and whenthe valve plug nears the wide open position, the change in flow rate approaches zero. In acontrol valve, the Quick Opening valve plug isused primarily for on-off service, but it is alsosuitable for many applications for which aLinear valve plug would normally be specified.PHPK models PV-60, PV-70, and CV (checkvalves) have quick opening plugs.

The linear flow characteristic curve shows thatthe flow rate is directly proportional to the valve travel. This proportional relationship produces a characteristic with a constant slope so that with constant pressure drop, the valve gain will be thesame at all flows. (Valve gain is the incremental change in flow rate produced by a correspondingincremental change in valve plug position. Gain is a function of valve size and configuration, system operating conditions and valve plug characteristic.) The Linear valve plug is commonlyspecified for liquid level control and for certain flow control applications requiring constant gain.PHPK models PV-80 and PV-90 are available with linear flow plugs.

In the equal percentage flow characteristic, equal increments of valve travel produce equal percentagechanges in the existing flow. The change in flow rate is always proportional to the flow rate just beforethe change in valve plug position is made. When the valve plug is near its seat and the flow is small,the change in flow rate will be small; with a large flow, the change in flow rate will be large. Valveplugs with an equal percentage flow characteristic are generally used on pressure control applications,and on other applications where a large percentage of the pressure drop is normally absorbed by thesystem itself, with only a relatively small percentage available at the control valve. Equal percentagevalve plugs should also be considered where highly varying pressure drop conditions can be expected.PHPK models PV-80 and PV-90 are available with equal percentage flow plugs.

It should also be noted that although PHPK flow control valve models PV-80 and PV-90 have shut-offcapability, a flow control valve should not be installed in a system as a shut-off valve.

Globe Valve Sizing InformationNote: The term CV is generally used by industry for comparing and calculating relative flow capacityin valves. Consideration should be given that calculated results are comparative only.

Definitions: CV equals the number of gallons per minute of water, having a specific gravity of 1.0, thatwill pass through the valve with a pressure drop at the valve of 1 PSI.

CV = valve flow coefficientP1 = upstream pressure in PSIAP2 = downstream pressure in PSIA*▲▲P = pressure drop or differential (p1-p2) in PSIS.G. = specific gravity relative to air or water

*When calculating gas or vapor flow and the calculated ▲▲P exceeds one-half the upstream pressure,use one-half the upstream PSIA as sizing ▲▲P.

PHPK Cryogenic Globe Valve Cv Data

Note: The flow capacity of a valve is defined by its Flow Coefficient (CV ), which is virtually constantfor any inlet pressure, pressure drop, temperature, flow rate, or fluid medium. The CV is equivalent tothe number of gallons per minute of water, having a specific gravity of 1.0, passed by the valve with a1 PSI pressure drop.

In addition to requirements for chemical and physical material certifications on all raw material and castings, additional performance tests are required by PHPK to guarantee the highest quality valves for cryo-genic and vacuum service.

Quality Tested

■ Body castings 100% radiographed

■ Body castings 100% liquid penetrant (Zyglo)

inspected

■ Proof pressure tested to code requirements

■ Leak tested across the seat

■ Mass spectrometer leak test at 1 x 10-9 scc/sec

helium

■ Operational test prior to shipment

■ Commercially cleaned using a pressure circulated,

filtered, PHPK-developed system

■ Specialty cleaning available on request

PHPK tests all valves utilizing PHPK-designed and developed test equipment.

In addition to raw material tests, operational and performance tests, PHPK valves have been proven as a performance leader by independent government tests.

ConclusionsThe test article was subjeted to 3 runs of cryogenic leak checks and 2 runs of ambient cyclingfor a total of 1,120 acutation cycles. The valve was found to be bubble-tight helium at -320degrees F and 250 psig. The handwheel torque required for bubble-tight shut-off at a giveninlet pressure was highly repeatable. The valve and manual operator worked smoothly andconsistently through all actuation cycles.

Complete and detailed stress analysis has been completed for the entire PHPK product line of cryogenic valves. Finite Element models of this product line have been developed and subjected tothorough analysis. Not only the valve bodies, but the barrel and extension tubes of all of these valvesare included in the analysis.

Results demonstrate that even the most critical local stresses in the valve bodies do not exceed 75% ofthe material Basic Allowable Stress at the design pressure of 600 psig. Further results demonstratethat the most critical local stress expected at the elevated test pressure of 900 psig (150% of designpressure) is only 73% of the Yield Stress.

Analysis Methodology

Finite Element modeling and analysis have been developed and analyzed using a commercially marketed and widely used personal computer based system. All the analysis are linear (e.g., assumestress/strain remains in the elastic range and strains are relatively small). PHPK drawings have beenmodeled.

All material properties have been taken from ASME Standards and incorporated in the computer-based Materials Library for analysis purposes.

Conclusions

Using contemporary Finite Element Analysis techniques, PHPK cryogenic valves have been subjectedto thorough and critical stress analysis. Detailed stress distributions clearly indicate the areas of high-est stress with even the most critical criteria demonstrating that all the valves meet the design criteriafor the specified design pressure of 600 psig. Furthermore, the results also demonstrate that all ofthese valves will satisfactorily pass the 900 psig Pressure Test.

TUBE SIZE CRYOGENIC GLOBE VALVES

DescriptionThe PHPK tube-size cryogenic globe and angle valves are manufactured with the same attention to detail and quality as their pipe-size counterparts. All manual tube-size valvesemploy smooth acting acme threads and six-bolt bonnets. Remote valves are designed toaccept a variety of actuators. All tube-size valves employ close tolerance barrel design, dual-seal warm O-rings, and all of the unique plating and other PHPK design features of the pipesize valves. Although designed primarily for on/off service, the PHPK tube-size valves canbe modified for flow control.

All specialized testing and material controls applicable to other PHPK valves are not relaxedduring the manufacture of the tube-size valve. This includes a unique one-piece seat designwhich can be field replaced in minutes and guarantees bubble tight shut-off.

2 -18

PHPK Tube-Size Valve Ordering SpecificationAll cryogenic extended-stem globe valves will be PHPK model TV-11, TV-13 or TV-85 series. All valve components will be totally interchangeable between valve models TV-11 and TV-13. Castings will be lost waxinvestment cast, ASTM A-743, grade CF3 (304L) stainless steel, radiograph and zyglo inspected. Valve compo-nent materials of construction will be 304L or 300-series stainless steel. Bonnets will be bronze alloy. All buttweld connections will be “true butt weld“ with no closed-end cavities (such as socket welds which can not beeasily cleaned for oxygen service). Weld connection between body extension tube and valve body casting willbe a butt weld connection (TV-11 and TV-13 only). Seal disk material will be Neoflon CTFE M-400H, (formerlyKel-F). Valve barrel and bonnet bolts will be plated with a PHPK-specified, patented nickel/teflon plating,which has been tested and approved for oxygen service. This plating, unlike chrome, does not chip or flake andprovides a homogeneous surface to prevent galling. The valve design will provide a close-tolerance fit (approxi-mately 0.003”) between the barrel and the body extension tube, allowing operation in any orientation, evenupside down, while ensuring bonnet (Viton, fluorocarbon rubber, O-ring) seals remain warm when the valve isin cryogenic service. Stem packing will utilize Viton O-rings on the static and dynamic areas of the sealing sur-faces. Bonnet seal will be a single Viton O-ring. Valves will have one-piece seat seals which do not require stak-ing or welding for assembly or maintenance. All vacuum jacketed valves will be serviceable without breakingvacuums. Stem packing in manual valves (TV-11) will be replaceable without removing the valves from service.

Easy Replacement Positive Shut-off Seat Seal Design

Like the PHPK pipe-size valves, the tube-size valves use a unique design, self-aligning, positive shut-off seat seal that is easy to maintain. Designed to provide a dead ended flowpath, and no risk of loss of parts into the flow stream.

Unlike other seat seal designs that have high-risk leak paths and questionable integritywhen field installed, the PHPK design is leak tight and requires no special skills to ensurethe valve integrity.

Like our standard cryogenic globe valves, PHPK helium service valves have been engineered,designed, and analyzed to provide the optimum in service and reliability to the specializedhelium market where low heat leak and high quality are standards. Patterned after the stan-dard service valves, all PHPK helium valves utilize all butt welded design for wetted surfaces.End connections are available in a variety of configurations. Pipe-size valves have undergonecomplete computer analysis and have been tested for a 300 psig, non-shock, WOG rating1.Tube-size valves are rated at 150 psig, non-shock, WOG rating1.

The same unique PHPK designs, materials, and manufacturing techniques are applied to theHPV/HTV series as to the PV/TV series, including controlled close tolerance gas path (.003” to.004”), allowing the use of simple, warm, mass spectrometer tight O-ring bonnet seals. PHPKhelium valves are available with bellows seals and intermediate LN2/GN2 heat stations asoptions. Completely interchangeable between manual, remote on/off and remote flow control.Field change-outs can be made without replacing the body assembly. Lower heat leaks arestandard because of increased length, lighter walls, and a unique stem extension design.

Design Features Include:

■ Higher flow coefficients than other Cryogenic Globe Valves

■ Low mass for rapid cool-down

■ Designed for reduced heat leak

■ Unique seat seals provide positive shut-off

■ Easy-to-maintain, top entry without vacuum loss

■ Easy-to-operate, patented plating process and low maintenance materials

allow for smooth operation and reliable service

1 actual service pressure should be specified at time of purchase
