DESCRIPTION
The E-CKCB is a pilot check valve. It has a non-sealed pilot, a steel seat, and is non-vented.
OPERATION
The E-CKCB valve allows free flow from the valve port 2 to the load port 1 and blocks flow in the opposite direction; Pressure at te pilot (port 3) will open the valve from port 1 to port 2. Pilot pressure needed at port 3 to open the valve is directly proportional to the load pressure at port 1. Pressure at port 2 directly opposes pilot pressure.
FEATURES
* Available only with 30 psi or 75 psi (2 bar or 5 bar) check valve cracking pressures.
* Extremely low leakage. The seat and poppet are heat treated for long life.
* Standard unsealed pilot allows air trapped in the pilot line to be purged from the circuit.
