SYMBOL
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 the power is off, E-SP16-20 is regarded as a one-way valve, allowing the oil to flow from 1 to 2 and stopping the oil from flowing from 2 to 1. When energized, the passage from 1 to 2 will be opened. The flow is proportional to the current applied to the coil. The emergency manual control option can also change the flow rate. Note: If lower voltages are used on the machine, a 12 or 24V system requires a 10 or 20 V coil, respectively.
