OPERATION

This is a proportional, non-compensated, 3 position 4 way, directional flow control solenoid valve, with float-center spool.

APPLICATION NOTES

These cartridge valves are typically applied to provide bi-directional, proportional control of hydraulic cylinders and motors. In applications requiring load-holding, PO checks or counterbalance valves can be added to provide a low leakage solution. For load-independent flow control, apply with a pressure compensator, such as CP700-4 (see Example Circuit). Port 1 should be used as the tank port, with a maximum backpressure of 150 bar. For applications with unequal flows, the highest flow should be connected to Port 2.

	Note: For optimal performance install with the solenoid valve
	below the tank oil level in the horizontal position, reducing the			Shown with Standard Coils,
	chance for trapped air in the valve.			Deutsch connectors
