Check Valves allow flow in one direction only, closing when the flow reverses. Ranging from 1/4" to 1" sizes with 1/2" NPT female x female connections. Made from 316 stainless steel.


Oliver Valves check valves are a spring loaded, fail close barrier. The sprung poppet arrangement has been designed to minimise the flow loss associated with check valves.

The check valves can be supplied as a stand alone valve or an integral assembly within a valve body such as a Double Block and Bleed valve for chemical injection purposes.

Our check valves as standard are rated to 413bar (6,000psi) with a cracking pressure of 0.5bar (7psi) and are available in a range of different materials.

3D Models are available upon request.
