Swing Wafer Check Valve


• Minimizes piping support with the compact wafer style body. The Huachao Swing Wafer Check Valves are two to three times lighter than traditional full-bodied check valves.

• To meet special applications and service conditions, Huachao 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, Huachao offers an external spring which eliminates the spring from the flow path. This will prohibit the possibility of fiber wrapping around the spring or chemical attack of the spring.

• Maintenance is minimal with the field replaceable O-ring seat, available in all styles and sizes.


The Huachao Swing Wafer Check Valve is used to stop flow reversal in chemical refineries, ammonia compressors, waste water treatment plants, HVAC systems and most other industrial applications.
