Welcome To Check Valves.co.in
 A Check valve is a mechanical device, a valve, that normally allows fluid (liquid or gas) 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. 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. The bodies (external shells) of most check valves are made of plastic or metal. |
Types of check valves
 |
Ball check valve
A ball check valve is a check valve in which the disc, the movable part to block the flow, is a spherical ball. In some (but not all) ball check valves. |
|
Diaphragm check valve
A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve. Pressure on the upstream side must be greater than the pressure on the downstream side by a certain amount. |
|
Swing check valve
A swing check valve is a butterfly-style check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. |
|
Clapper valve
A clapper valve is a type of check valve used in firefighting, and has a hinged gate (often with a spring urging it shut) that will only remain open in the outflowing direction. |
|
Lift-check valve
A lift-check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. |
|
Stop-check valve
A stop-check valve is a check valve with override control to stop flow regardless of flow direction or pressure. When the valve is open, it acts as a check valve, but the valve can be deliberately shut to stop flow. |
|
Plastic check valves
The patented diaphragm in the Plast-O-Matic True Blue Check Valve is designed to re-seat with a bubble tight seal regardless of mounting position or reverse flow |
|
Brass check valves
Use of check valves also allow maintenance to be performed down line without losing pressure in the system ahead of the maintenance. |
|
