PSV12-34-05 Proportional Valve
English Chinese (Simplified)

comatrol hydraulic cartridge valves


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


This is an electro-proportional directional control using a 3-Position, 4-Way design for directional control of hydraulic cylinders and motors. For load-independent flow control, apply with a pressure compensator, like CP701-4 (see Example Circuit). Port 1 should be used as the tank port, with a maximum back-pressure of 150 bar. The highest return flow coming from a cylinder should be connected to Port 2.

Use the available Comatrol Adapter Block to help test and replace proportional CETOP D03 - available in compensated or non-compensated. Select the robust coil for those extreme environmental conditions - voltage extremes, high temperature, shock & vibration, chemicals, and/or water ingression.

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.
