IntroductionChampion Valves, Inc. (CVI) Models NZ and NZS axial flow nozzle check valves are engineered to provide the longest and most reliable protection of gas and liquid piping systems. CVI’s axial flow non-slam design minimizes water hammer and associated pressure transients. Our design is energy efficient, has an extremely long service life and requires minimal maintenance costs over the life of the valve.

Models NZ and NZS axial flow nozzle check valves are designed with a spring-loaded, center-guided, profiled disc that is guided through bearings in the valve body guide. The valve body is a streamlined axial design with a central diffuser that reduces pressure loss through the valve. Using the latest simulation software and applying years of application experience, Models NZ and NZS have one of the most efficient pressure drop designs available today.

Our commitment to continuous design improvements has led to many unique features, including a hexagonal shaft design that ensures smooth travel of the disc.

FEATURES BENEFITS

• The geometry of the valve’s body and disc are designed using Computational Fluid Dynamics to streamline the flow path • Internal diffusers hold the guide to the body• Spring is engineered based on specific operating conditions

Non-Slam Design

• Lightweight, singular compression spring-loaded disc• The disc travels only a short distance from the open to closed position

Axial Flow Path/Venturi Effect

Reliable Operations

• Conical disc is self-aligning• Disc is the only moving part• Large valves feature front and rear bearing supports• Unique hexagonal shaft provides a passageway for suspended particulate to flow through shaft/bearing area, while simultaneously reducing drag• Multiple material and trim options available

• Reduces operating cost with minimal pressure drop• Reduces cavitation• Reduces risk of damage to piping

• Provides fast dynamic response• Ensures consistent non-slam operation• Provides optimal surge protection for centrifugal compressors

• Designed for gas and liquid media• Provides consistent smooth travel of shaft through guide bearings • Ensures low seat leakage rate over a long period of time with aligned disc/shaft • Ensures low maintenance costs• Optimizes installation - can be mounted in any piping orientation (Contact factory for vertical down flow installation).

Design Features

Unique Shaft Design Small clearance and tolerances between the shaft and bearings ensure smooth operation of the disc during opening and closing of the valve. Our unique hexagonal shaft provides a passage way for entrained particles in the media to flow through the shaft/bearing area for consistent alignment of the disc to the body seat. This prevents potential wear in the guide bearing area and prevents increased drag forces.

Shaft SupportSupport of the shaft is required to ensure consistent alignment of the conical disc. This results in a consistently low seat leakage rate and eliminates axial deflection of the shaft due to the weight of the disc. A dual bearing support system is used based on specific disc/shaft weight and is standard for 12” and larger.

Single Body Structure - No External Leakage


Hexagonal Shaft Detail

Single Support Structure Dual Support Structure

CVI Models NZ and NZS utilize a patented independent front-loading sealing ring technology. The seat is located on the sealing ring that is secured internally in the one-piece body. The flange face is not interrupted. This results in zero leakage outside of the valve body and allows for precise machining of the sealing face for a consistently low seat leakage rate.

Seat DesignCVI Models NZ and NZS axial flow check valves are available with a metal to metal or soft seat. Metal seats have dissimilar metals for protection against galling. The soft seat design has zero seat leakage down to 5 psig backpressure. Models NZ and NZS have a fire-safe tested seat design. A wide variety of seat material combinations are available for different media and temperatures from - 450 °F to 1000 °F.

Models NZ and NZS axial flow check valve’s low, energy saving pressure drop through the valve is designed using Computational Fluid Dynamic software to ensure an efficient and streamlined flow passage and to minimize fluid turbulence. Diffusers in the valve body contribute to a streamlined flow with minimal cavitation and minimal noise.

Using Bernoulli’s principle, the high flow rate in the seat area creates a low pressure zone behind the disc which compensates for the engineered spring. The spring is designed based on actual flow conditions to allow the valve to be fully open at low flows. A high rate of pressure recovery results in a fast response to dynamic changes in the media flow. This allows the valve to open at a low cracking pressure and reach full open at reduced flow rates. Flow coefficients have been verified by independent laboratory flow tests.

Working Principles & CharacteristicsStreamlined Flow Passage Design - Low Pressure Loss

Non-Slam Performance

The rate of fluid deceleration when a pump is turned off can exceed the percentage of disc closure, resulting in reverse flow. Sudden closure of a check valve with a reverse flow causes water hammer. CVI’s axial flow check valve’s single compression spring-loaded disc reacts quickly to fluid deceleration. The disc’s short travel distance from full open to close, before reverse flow begins, ensures non-slam performance. Design of the spring torque is fundamentally important for reducing potential water hammer. CVI designs the spring for each specific application using the latest simulation software and years of application experience.

Opening Surge Protection

CVI’s axial flow check valve’s integrity is not affected by fast opening forces that can occur with centrifugal compressor surge or fast start-up pumps. The amount of force that can be generated by the disc to the valve’s internal guide is shown in the formula below. Derived from Newton’ s Second Law, as the distance the disc travels from the open to closed position increases so does the force of impact. The short stroke length reduces the distance necessary for acceleration, reducing the impact force and protecting all of the valve’s internal components from the initial opening surge.

Manufacturing

Each valve must pass CVI’s standard high quality inspection and testing procedures, and any additional customer requirements. All castings are subjected to tensile, impact testing and mass spectrometer analysis. The test samples and associated foundry and in-house material test reports are fully traceable. Inspection hold points are established during the manufacturing process to ensure your valves are delivered on time. All valves are hydrostatically tested in accordance with established industry standards and as specified in the customer’s purchase order.

MODEL SDX

SINGLE DISC

WAFER CHECK VALVE

TM

A weight kit is supplied with every valve. The smallest weight in the kit increases total cracking pressure to 0.5 psi. Subsequent weights increase cracking pressure to 0.75 psi and 1.00 psi. For example, for a 4” SDX valve, Weights D (0.50), E (0.75) & F (1.0) are supplied. Selecting Weight E results in a total cracking pressure of 0.75 psi. The 2” SDX initially has a cracking pressure of 0.5 psi, thus only including the weights for 0.75 psi and 1.00 psi cracking pressure.
