INTS10-36 Proportional Electric Reducing/Relieving

A screw-in, cartridge-style, pilot-operated, spool-type reducing/relieving valve, which can be infinitely adjusted across a prescribed range using a variable electric input. Pressure output is proportional to DC current input. This valve is intended for use as a pressure limiting device in demanding applications.

With current applied, the valve blocks flow from port 2 to port 1 until sufficient pressure is present at port 1 to open the pilot section by offsetting the electrically induced solenoid force. Increasing electric current will increase the control (reduced) pressure at port 1. With no current applied to the solenoid, the valve will relieve pressure at port 1 at approximately 6.9 bar (100 psi), regardless of pressure at port 2. The valve has an optional manual override feature. This allows the valve to be set when the electric supply is lost. The manual setting is added to the electric setting, so when using the manual override feature to establish a minimum setting, care is required to prevent the system from becoming over-pressurized.
