CHECK VALVES

A swing check valve uses a hinged disc that moves with the direction of flow, while wafer check valves use a compact disc or plate arrangement installed between pipeline flanges. The appropriate design depends on factors such as pipeline configuration, pressure, flow conditions, installation space, and application requirements.

Yes. FEVISA offers check valve designs for demanding pressure applications. Its published check valve documentation includes pressure classes such as 150, 300, 600, 900 and 1500, while its forged piston check valve range includes 800 Class configurations.

To select the right industrial check valve, consider the process media, flow direction, valve size, pressure rating, operating temperature, installation position, material compatibility, end connection, and required standards. The application and flow conditions should be evaluated to determine whether a swing, piston, wafer, dual-plate, or non-slam check valve is most suitable. Working with experienced check valve suppliers can help ensure the correct valve is selected for reliable backflow prevention and long-term performance.

Forged piston check valves are commonly used in high-pressure industrial applications where reliable backflow prevention is required. FEVISA provides forged piston check valve configurations with bolted, welded, and pressure-seal bonnet options.
