What is a Wafer Type Non-Return Valve?
A Wafer Type NRV is a flangeless valve that is "sandwiched" between two pipe flanges. Unlike traditional flanged check valves, the wafer design uses the pipe flange bolts to secure the valve body in place. This results in a significantly shorter "face-to-face" dimension, making it the preferred choice for space-constrained environments.
Key Advantages:
- Compact & Lightweight: Reduces the total weight of the piping system and requires less structural support.
- Cost-Effective: Less material usage in manufacturing translates to a more economical price point without compromising quality.
- Low Pressure Drop: Streamlined internal design ensures high flow efficiency and minimal energy loss.
- Easy Installation: Simplifies the setup process as no specialized flange gaskets are required beyond those used for the pipe flanges.
- Versatile Response: Engineered for quick response times to prevent water hammer and protect upstream equipment.
Types of Wafer Check Valves We Manufacture
FlowBiz Exports specializes in a broad spectrum of wafer-style non-return valves tailored for specific industrial needs:
- Dual Plate Check Valve (DPCV): Features two spring-loaded plates that close before flow reversal, virtually eliminating water hammer.
- Single Disc Wafer Swing Check: A simplified, space-saving version of the standard swing check valve.
- Tilting Disc Check Valve: Optimized for rapid closure and reduced slamming.
- Silent/Nozzle Check Valve: Axial flow design for noise-sensitive environments.
- Wafer Check Valve with PTFE Disc: Ideal for pharmaceutical and food-grade applications requiring high chemical resistance.
Spotlighting the Dual Plate Check Valve
As a specialized subtype, the Dual Plate Check Valve is the flagship of the wafer family.
- Design: Two hinged discs swing open with forward flow and are assisted by a central spring to snap shut during flow deceleration.
- Efficiency: It offers a more streamlined flow path compared to a single disc, reducing turbulence and improving overall system $C_v$ values.
- Durability: The split-disc design distributes the pressure load more evenly, extending the life of the internal components.
