Check Valves

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, the check valves are made from 316 stainless steel.

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

For chemical injection purposes, 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.

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.

Our range can be supplied individually or fitted to a valve, giving the customer flexibility with their instrument valve requirements. If you would like more information about the instrument valve accessories we supply, please contact Oliver Valves today.
