PRODUCT DESCRIPTION

The purpose of check valves is to prevent backflow within a piping system. Check valves are unidirectional valves that provide unobstructed flow in one direction as long as flow pressure remains constant and protect the piping system against reverse flow.
Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a one-way valve, in which the flow can run freely one way, but if the flow turns the valve will close to protect the piping, other valves, pumps etc.

There 2 main types of PPR check valves

1.PPR BALL CHECK VALVES

Ball check valves are lift check valves, and use a weighted ball rather than a disc to allow flow and inhibit backflow. Once the cracking pressure is attained, the ball lifts up from its seat, allowing flow to occur. When there is a reduction of flow pressure, it falls back into place to prevent backflow.

2.PPR STOP CHECK VALVES

Stop check valves combine the benefits of lift check valves with the positive closure functionality of globe valves. These features allow for the control of flow regardless of direction. The main purpose of stop check valves is to prevent damage to pump or boiler systems .
