TS90-SG34

PRESSURE RELIEVING DROP-IN VALVE

Overview

Description

The TS90-SG34 is a drop-in pilot operated (two stage), spool type hydraulic relief valve with pilot flow vented at port 3. It is a 3rd generation hydraforce 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 inversely proportional to the input electrical current.

Operation

TS90-SG34 is a spring biased valve that blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to open the valve by overcoming the preset induced by pilot spring force. With no current applied, the valve will relieve at the maximum pressure setting. Applying current to the coil decreases the induced spring force, thereby reducing the valve setting. port 3 provides drain of pilot flow to the tank.
