    Designed to provide customers with the widest selection of sizes, orificesand construction materials, Series 2700 meets the exacting demands of theprocess industry.

    Superior Design A single design handles air, steam, vapor and

    liquid services. Maximum interchangeability of parts affords easy

    maintenance and lower costs. Fixed blowdown design simplifies testing and

    repair. Maximum blowdown of 5% to 15% regardless of service.1

    A built-in lift stop ensures stable performance. Balanced design in C and D orifices nullifies

    the effects of back pressure on set point.

    ASME Code Certification Manufactured in conformance to Section VIII of

    the ASME Boiler and Pressure Vessel Code for air, steam, and liquid service.

    Capacities certified by The National Board of Boiler and Pressure Vessel Inspectors.

    Optional O-Ring Seat Design O-ring seat design available for maximum

    seat tightness. Teflon available at higher pressures to provide

    the same zero bubbles per minute leakage as elastomer O-ring seats.

    Comprehensive Product Line Set pressures from 15 psig to 6500 psig with

    orifice areas from 0.068 to 0.573 sq. in. Standard valves have MNPT inlet X FNPT outlet.

    Optional female thread, flanged, socket weld, welding nipple, and sanitary connections available.

    Maximum Selection of Materials Standard construction includes 316 stainless steel

    body, trim and spring, with carbon steel bonnet. Optional materials include Monel, Hastelloy C,

    and materials suitable for NACE service.

    Ordering Information

    3

    Selecting and specifying Farris pressure relief valves is simple using the numberingsystem that follows. Each digit of the part number has a distinct significance. Thedigits describe the basic valve series, orifice, seat design, inlet temperature range,body, bonnet and spring material, inlet type and pressure rating.

    General Notes:1. Not all combinations of inlet and outlet sizes shown are available.

    Consult the selection tables of pages 6 and 7.2. Test gag option is not available with open lever cap.3. Available in O-ring seat design only. Consult the Farris Factory.

    Do you have variable back pressure? Cant use a balanced bellows design? Farris has the solution with the Series 2700 balanced design pressure relief valve. The balanced effect isachieved by isolating the upper valve chamber and eliminatingany back pressure build-up in the bonnet effecting valve set pressure.

    These valves are available in 1/2, 3/4 and 1 inlet sizes with a1 outlet and two orifice areas. Pressure ranges from 15 to 1480psig, standard soft seat design. Flanged and welded inlet andoutlet connections are available with the same material options as the standard design.

  • O-ring Selection

    The 2700 Series is available with an optional O-ringseat which minimizes fugitive emissions and costlyproduct loss. This optional seat construction provides zero bubbles per minute leakage at 90%

    of set pressure per API Standard 527. The Tablesbelow list the set pressure and temperature rangefor both the elastomer and Teflon seat options.

    PRESSURE & TEMPERATURE L IMITS O -RING SEAT VALVE

    General Notes:1. Maximum O-ring set pressure limit cannot

    exceed the pressure limit for a given type number and size as indicated in the metalseat selection tables.

    2. Temperature range may vary depending on service fluid.

    3. Ethylene propylene is suitable for steam service up to 350F, Teflon up to 500F.

    4. Consult the Farris Factory for other materials.

    General Notes:1. Available with optional elastomer or Teflon seat design as illustrated. Change

    the fourth digit of the type number from A to C for soft seat, A to T for Teflon. Example: 27DC23-M20 for soft seat, 27DT23-M20 for Teflon. See Selection Table for pressure and temperature limits.

    2. Above type numbers indicate standard materials of construction. To select corrosive or low temperature materials, add type number suffix as indicated on pages 3 and 9.

    3. Available in materials suitable for sour gas (H2S) service to NACE Standards MR0103 and MR0175 / ISO 15156. Add "N1" (standard materials) or "N4" 7

    (all stainless construction) to the type number. Example 27DA23-M20/N1 & 27DA23-M20/N4.

    4. For open or packed levers, change the second digit of the type number suffix.Examples: 27FA45-M70 for open lever, 27GA46-M40 for packed lever.

    5. For socket weld or welding nipple connections, change the first digit of the typenumber suffix to S for socket weld or W for welding nipple inlet and outlet.Examples: 27DA33-S20 for socket weld, 27DA33-W20 fo welding nipple.6. Female threaded inlet available. Change first digit of type number suffix to F. Example: 27EA-34-F20.

    7. For set pressures below 15 psig, consult the Farris Factory.

    General Notes:1. Any part denoted with a dash is standard material.2. For S4 trim, a 17-4 Ph. or 17-7 Ph. spring may be necessary for some pressures and temperatures.3. For open and packed lever materials, see page 16.4. Maximum set pressures for S4, M4, and H4 trim are the same as the carbon steel valves or the

    316 St. St., Monel and Hastelloy C flange limits respectively, whichever is lower.5. Temperature for balanced or O-ring seat design is limited by the elastomer selected. For Viton O-rings,

    the temperature range is -20F to +450F. For other materials, consult chart on page 6.6. Hastelloy and Hastelloy C are registered trademarks of Haynes International. Monel, Inconel and
