DESCRIPTION
The E-4CK120 is a pilot-to-open check valve, allows flow in one direction, low pressure drop, before the application of control pressure, prevent the flow in the opposite direction.
OPERATION:
Pressure on the valve port 2 causes the spool to overcome the spring force, allowing oil to flow to the cylinder port 1, and the spool prevents reverse flow. The pressure of the hydraulic control port 3 overcomes the pressure of the oil port of the oil cylinder, so that the valve poppet is lifted away from the valve seat and the oil is allowed to flow from the oil cylinder to the oil port of the valve.
FEATURES
* Hardened seat for long life and low leakage.
* Optional sealed piston.
* Optional spring ranges.
* Compact size.
