Check Valves

Check Valves

Non-return (one way) check valves.

Single spring and double check valves can be installed in a horizontal or vertical position. Double check valves are often a local authority requirement in plumbing installations.

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