Swing Double Disc Check Valve

Specifications:

The swing flex check is designed to be maintenance-free and has superior performance compared with traditional swing check valves. The disc is the only moving part of the valve, and it can be easily replaced without removing the valve from the pipeline. Its unrestricted full flow design makes swing flex check an excellent choice for slurries and sludges, even in vertical upward flow applications. The non-impact performance is ensured by placing the valve seat at a 45° angle, thereby minimizing the disc stroke. When used with the optional rubber lining, our swing flex check is ideal for high-wear and corrosive applications. Independent process, cycle and performance test report certification can be provided upon request.

The cover-mounted Disc Position Indicator clearly indicates the valve's disc position. A proximity limit switch can also be provided to indicate open/closed position to a remote location.A Backflow Actuator is available for use when manual backflow operation is required. Common applications are for priming pumps, back flushing, draining lines, and system testing.
