H76 Wafer Dual Plate Swing Check Valve
- Dual Plate, Spring-Loaded: Its core advantage is the dual-disc design with spring-assisted closing, which enables fast shut-off, effectively eliminates water hammer, and protects the pipeline system.
- Ultra-Thin, Space-Saving: Its face-to-face length and weight are far less than those of conventional check valves, facilitating easy installation and significant savings in space and cost.
- Low Flow Resistance: The discs open smoothly, providing a wide flow path with minimal fluid resistance.
- Flexible Installation: Suitable for both horizontal and vertical pipeline installations.
- Reliable Sealing: Available with either soft or metal-to-metal hard seats to accommodate different operating conditions.
The H76 Wafer Dual Plate Swing Check Valve is an ultra-thin check valve characterized by its two spring-loaded, semi-circular discs. The valve is installed by being clamped between pipeline flanges, resulting in a very compact structure. In operation, fluid pressure pushes the two discs open to create a flow path; upon flow stoppage or reversal, the discs close instantly under spring force. This dual-disc, spring-loaded design leads to an extremely short closing stroke, making it highly effective at preventing water hammer and ensuring quiet, smooth operation. It is primarily used in water supply and drainage systems, fire protection, high-rise buildings, and industrial pipelines where space is limited.
