This is a direct-acting, spool-type, proportional, pressure reducing/relieving valve. It is a drop-in, flange mounted cartridge type valve for use with mineral based or synthetic (with lubricating properties) hydraulic fluids. The coil is an integral part of the valve and is not serviceable. The regulated pressure is proportional to the input electrical current in the pressure ranges shown.
The EHPR98-T33 allows free flow from 1 to 3 when no current is applied to the coil. When the coil is energized, 2 is connected to 1. Increasing current applied to the coil will increase the control (reduced) pressure proportionally. If pressure at 1 exceeds the setting induced by the coil, pressure from 1 is relieved to 3.
note: back pressure on port 3 becomes additive to the pressure setting at a 1:1 ratio.
