Proportional Valves Technical Information
Proportional Directional
PSV10-34-05
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 chance for trapped air in the valve.
