Wafer check valve
The Wafer Check Valve is designed for use in pipeline systems where space is limited. Its compact wafer-style body fits between flanges, offering fast response to flow reversal. The valve prevents backflow, reduces water hammer, and ensures operational reliability in water, oil, gas, and industrial fluid applications.
Wafer check valve
Wafer Check Valves are engineered for compact installation and efficient backflow prevention. Featuring a lightweight wafer design, the valve fits directly between flanges, reducing installation space and weight compared to traditional swing check valves. The valve disc responds quickly to flow reversal, minimizing pressure surges and protecting pumps, compressors, and pipeline equipment.
Constructed from durable materials including carbon steel, stainless steel, and alloy steel, the valve can handle a variety of media under moderate to high pressure. Suitable for horizontal and vertical installations, wafer check valves are ideal for water treatment, petrochemical, power generation, and general industrial applications.
Wafer Check Valves are manufactured and tested according to international standards:
