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

Standard Check Valves

Standard check valves, suitable for most applications, have fully guided poppets which always block flow from 2 to 1.  They are spring biased closed until sufficient pressure is applied at 1 to open flow 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 orifice for free flow in one direction and controlled flow (speed) in the opposite direction.

 

Reverse Flow Check Valves

Reverse flow check valves, useful for Reverse flow check valve higher pressure applications or where housing or size constraints require this flow path are also available. These valves have guided poppets that block flow from 1 to 2 and are spring biased closed until sufficient pressure is applied at 2 to open flow to 1.
