Cartridge valve HY-TS98-31

electrichydraulicpilot-operated

A screw-in, cartridge-style, pilot-operated, spool-type hydraulic pressure reducing/relieving 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. Operation: Without applied current, the TS98-31 allows dual-flow from③ to ④ while blocking ②. when the coil is energized, ③ is connected to ②, and pressure at ③ is controlled proportional to the amount if current applied to the coil. If pressure at ③ exceeds the setting induced by the coil, pressure is relieved to ④. Back pressure on port ④ becomes additive to the pressure setting at a 1:1 ratio. Note: consult factory for special OEM variations of this product.
