HY-TS10-36 (Proportional Pilot-operated Pressure Reducing/ Relief Valve)

A screw-in, cartridge-style, pilot-operated, spool-type hydraulic reducing/ relief 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 to the valve coil, the TS10-36 blocks flow from ① to ② until sufficient pressure is present at ① to open the pilot section by offsetting the electrically induced solenoid force. Increasing electric current will increase the control (reduced) pressure at ①. With no current applied to the solenoid, the valve will relieve pressure at ② at approximately6.9bar (100psi),regarding of pressure at ①. The TS10-36 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 of required to prevent the system from becoming over-pressurized.

Installation position

When possible, the valve should be mounted below the reservoir oil level. This will maintain oil in the armature preventing trapped air instability. If this is not feasible, mount the valve horizontally for best results.
