Description

A screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve, which can be infinitely adjusted across a prescribed range using a variable electric input. Pressure output is to DC current input. This valve is intended for use as a pressure limiting device in demanding applications. Operation: The HY-EHPR08-33 free flow ① to ③ when no current is applied to the coil. When the coil is energized, ② is connected to ①. Increasing current to the coil will increase the control (reduced) pressure proportional. If pressure at ① exceeds the setting induced by the coil, pressure from ① relieved to ③. Note: back pressure on ③ becomes additive to the pressure setting at a 1:1 ratio.
