SYMBOL
DESCRIPTION
Threaded, 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 may be used as a pressure limiting device in the apparatus.
OPERATION
E-SR4P2-B2 blocks the flow from 1 to 2 until port 1 has sufficient pressure to open the pilot section by counteracting the electromagnetic drive. The starting pressure can be set with a manual control when the valve is de-energized. The final pressure is the manual setting plus the motorised setting.
FEATURES
* Industry common cavity.
* Continuous-duty rated coils.
* Hardened precision spool and cage for long life.
* Optional waterproof E-Coils rated up to IP69K.
