flow control solenoid valve, with closed-center spool.
APPLICATION NOTES
These cartridge valves are typically applied to provide bi-directional,
proportional control of hydraulic cylinders and motors where low
leakage is not required. For load-independent flow control, apply with
a pressure compensator, such as HLE10-OPO (see Example Circuit). Port
1 should be used as the tank port, with a maximum back-pressure 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.
