Product Overview
Cartridge
Description
This valve is a pilot to open check valve. It has a non-sealed pilot, a Delrin seat, and is non-vented. It allows free flow from the valve (port 2) to the load (port 1) and blocks flow in the opposite direction. Pressure at the pilot (port 3) will open the valve, allowing flow 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
Provides hose break protection, prevents loads from drifting and positively locks pressurized loads.
Standard unsealed pilot allows air trapped in the pilot line to be purged from the circuit.
Optional external porting out of the hex end of the cartridge is available for external piloting. In this configuration, port 3 is blocked. See Control options E, and P.
Pilot-to-open check cartridges are locking valves, not motion control valves. For motion control applications, use counterbalance valves.
The Delrin seat is suitable for dirty, medium pressure systems that are not subjected to high flows or temperatures.
Extremely low leakage. If the load drifts due to the valve, the seat has probably been damaged by contamination and the valve should be replaced.
For models with manual load release control option, turn load release clockwise to release load.
