Check Valves

Check Valves

A check valve is one-way valve, in which the flow can run freely one way, but if the flow turns the valve will close.

Swing check valves usually require installation in a horizontal position or vertical position with the flow going upwards.

Single spring and double check valves can be installed in a horizontal or vertical position.

Double check valves have two internal non return valve mechanisms, they are often needed as part of a plumbing system in order to comply with plumbing regulations.
