Wafer Swing Check Valve ENQUIRY! Categories: Check Valve, Swing Check Valve, Wafer Check Valve Tags: Non Return Valve, NRV Valve, Swing Check Valve, Wafer Check Valve, What is a Valve Description Description Wafer Swing Check Valve gets its name from its wafer-thin design. These valves are sleek and made to fit in tight spaces between two flanges. There are no controls on this valve. The main component of the valve is a swinging disc in the center that opens in one direction and closes if liquids flow back in the other direction. How does a Wafer Swing Check Valve work? The valve’s wafer-like profile makes it a great choice for systems requiring short takeout lengths. Wafer check valves work much in the same way as swing check valves. Like swing check valves, wafer check valves are comprised of a disc and a seating arrangement. When material flows in one direction, the flow lifts the disc from the seating arrangement. This allows the material to flow through the valve. If and when flow reverses direction through the valve, the flow of material pushes the disc back into the seating arrangement, thus closing the valve off from the flow of material. Wafer check valves are designed to be slim and unlikely to clog. This design makes them ideal for use with materials containing solid particles or debris. This type of valve can be mounted either vertically or horizontally, as long as the back pressure required to seat the check valve is sufficient. Mechanisms are available to help provide assist valves in case back pressure is insufficient. Applications of Wafer Swing Check Valve Steam Hot & Cold Water Power & Heat Engineering Pressurized Air Industrial Technologies Fluids without Acidity or Alkalinity Properties Advantages of Wafer Swing Check Valve Minimizes piping support with the compact wafer-style body. This range of wafer check valves is two to three times lighter than traditional full-bodied check valves. To meet special applications and service conditions, These valves can be offered with many different options, such as silicone-free cleaning, oxygen-cleaning, vertical service, left-hand operation, levers, weights, and cushions. For media containing fibrous matter or caustics, These offer an external spring that eliminates the spring from the flow path. This will prohibit the possibility of fiber wrapping around the spring or a chemical attack on the spring. Maintenance is minimal with the field-replaceable O-ring seat, available in all styles and sizes. Related products Axial Check Valve Read more ENQUIRY! Dual Plate Check Valve Read more ENQUIRY!
