H76W Wafer check valve
The Wafer Check Valve is designed for efficient one-way flow control in pipelines. Its slim, wafer-style design allows installation between flanges without additional space. Featuring corrosion-resistant materials, rapid disc closure, and minimal pressure drop, it ensures dependable backflow prevention for water, oil, gas, and industrial fluid applications.
Wafer check valve
The Wafer Check Valve is a compact, lightweight solution for backflow prevention in medium and high-pressure pipelines. Its wafer-style design allows it to be installed directly between flanges, saving space and reducing weight compared to traditional swing or lift check valves.
Constructed from durable materials with corrosion and wear resistance, the valve ensures fast closure to prevent reverse flow and water hammer effects. Suitable for a wide range of media, it is widely applied in water supply, HVAC systems, chemical plants, oil and gas pipelines, and power generation facilities.
