DESCRIPTION
Proportional, solenoid-actuated, 2-way, seated, normally closed, hydraulic threaded cartridge valves for shut-off or load holding applications requiring low leakage.
OPERATION
When de-energized, the E-SP08-20X acts as a check valve, allowing flow from 1 to 2, while blocking flow from 2 to 1. When energized, the poppet lifts to open the 2 to 1 flow path, and the flow rate will be proportional to the current applied to the coil. Emergency manual control can also change the flow. Note: When used at lower voltages, 12 or 24 systems use 10 or 20 V coils respectively.
The back pressure of oil port 4 is added to the pressure set value.
