Swing 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.
Check valves are automatic valves that open with forward flow and close with reverse flow

Check valve model representation method Check model preparation instructions Check valve (one-way valve) model compilation instructions: Check valve (one-way valve) is also called check valve or reverse flow valve. It is an automatic valve that opens or closes the disc through the flow of the medium itself, and can only flow in one direction and […]
THINKTANK specializes in control valve, self-operated pressure regulator, breather valve, fusible link valve, certified with ATEX, PED, CE, UL/FM.
A swing check valve allows full, unobstructed flow and automatically closes as pressure decreases. Turbulence and Pressure drop are very low.
A Piston Check Valve is essentially a lift check valve. It has a dash-pot consisting of a piston and cylinder that provides a cushioning effect.

Types of Check Valves A Ball Check Valve is a Check valve in which the closing member, the movable part to block the flow, is a spherical ball. In some ball check valves, the ball is spring-loaded to help keep it shut. For those designs without a spring, reverse flow is required to move the…
Retract resistor check valve application: pneumatic cylinder, piston driven by Compressed air through 2 Retract resistor check valves. "A check valve, clack valve, non-return valve or one-way valve is 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, 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. Heart valves are essentially inlet and outlet check valves for the heart ventricles, since the ventricles act as pumps." [Check valve.
