Model EN043-PRR -Direct Acting Proportional, Pressure Reducing/Relieving, Slip-In Type

Special cavity, slip-in style flange retained, direct acting proportional pressure reducing/relieving valve. OPERATION: The EN043-PRR generates a variable pressure in response to a PWM (Pulse Width Modulated) current signal. With no current applied to the proportional solenoid, the inlet port #2 (P) is blocked and the regulated port #3 (U) is vented to port #1 (T). As current is increased, fluid pressure is proportionally controlled at the regulated port #3 (U). On attainment of proportionally determined pressure at #3 (U), the cartridge shifts to block flow at #2 (P), thereby regulating pressure at #3 (U). In this mode, the valve also will relieve #3 (U) to #1 (T) at a variable value over the set reducing pressure.
