Check Valves Technical Information

Application Notes

BASIC OPERATION

Check valves allow free ow in one direction and block ow in the opposite direction.

Check valves

STANDARD CHECK VALVES

REVERSE FLOW CHECK VALVES

Standard check valves, suitable for most applications, have fully guided poppets which always block ow from 2 to 1. They are spring biased closed until sucient pressure is applied at 1 to open ow to 2. This pressure is commonly called the crack pressure. Several crack pressures are available for each model. Consult check valves section for details. This valve is also available with an integral orice for free ow in one direction and controlled ow (speed) in the opposite direction.

higher pressure applications or where housing or size constraints require this ow path are also available. These valves have guided poppets that block ow from 1 to 2 and are spring biased closed until sucient pressure is applied at 2 to open ow to 1.

Check Valves Technical Information

Application Notes

SLIPIN CHECK VALVES

INLINE CHECK VALVES

APPLICATIONS

Slip-in style check valves are cartridges that drop into small cavities and are retained by SAE plugs or by other cartridge valves. They are ideal for use in manifolds where space savings is critical. Versions of these valves with Delrin® seats are also available for applications requiring extremely low leakage.

Also available are in-line check valves, which can be used to simplify machine plumbing.

Check valves have many common

applications including:

· Low pressure relief valve

· Bypass for lter elements

· Logic for load-sensing circuits

· Anti-cavitation or make-up

· Load holding (refer to Motion Control Valves for more information)
