DESCRIPTION
Threaded cartridge, pilot-operated hydraulic relief valve with variable input for continuous adjustment within specified range. The output pressure is proportional to the DC current input. The valve can be used as a pressure limiting device in the device.
OPERATION
The E-TS12-27 blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to open the pilot section by offsetting the electrically induced solenoid force. With no current applied, the valve will relieve at maximum set pressure.
NOTE: This valve is for hydraulic fan driven equipment.
