Swing Check Valves
A swing check valve allows forward flow and blocks reverse flow. It provides a strong option for uni-directional homogenous flow applications. The swing check valve’s disc and the rocker connect, allowing them to revolve at an angle around the pin shaft. When the input pressure on the disc exceeds the resistance pressure, fluid flows in the prescribed direction. While the valve opens, the disc separates from its seat and rotates around the pin to a fully open position. When the flow rate drops, the valve disc will rotate back to the closed position. This prevents backward fluid flow.

Disco Check Valves / Dual Plate Check Valve
Disco check valves are designed to block media on one side of the pipe within allowable pressure and temperature limits and to be installed in a pipe system only. They have only to be used on fluids to which the material and the seals are resistant.
Dual Plate Check Valve Consisting of 2 discs attached to the valve body by a pin and operated by the action of springs, which immediately start closing the valve when the fluid stops, dual plate check valves are used to prevent backflow and also work as a water hammer.
