- Supplier Information
A check valve is a mechanical device which allows any kind of fluid to flow through it in a single direction. Labline check valves are soft seated valves planned to supply unidirectional stream with rigid shut-off to back flow. Our check valves are perfect to trim down flow resistance and pressure drop to the lowest possible level. They are completely engineered, lapped and screwed in seat to ensure tight shut-off and long life. The hinge less design ensures simple operation, overcoming many of the problems experienced in swing check valves.

It is a mechanical device, a valve, that normally allows fluid (liquid/gas) to flow through it in only one direction.
Check Valve 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. Check Valves are often part of common household items. Although they are available in a wide range of sizes and costs, many check valves are very small, simple, and/or cheap.
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.
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.
