316 Stainless Steel 2 piece BSP threaded in line lift check valve. Suitable for a wide range of media including steam, water and oil. Please bear in mind that this is a metal to metal seat so a bubble tight seal will not be formed at lower pressures. Can be installed in any orientation as it has a spring backing. Great for a simple backflow / backpressure preventer where stainless steel is required.

A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid to flow through it in only one direction.

Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications.  Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive.

Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal.

An important concept in check valves is the cracking pressure, which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
