ITS10-27 Piloted Relief Valve

A screw-in, cartridge-style, pilot-operated, spool-type hydraulic relief valve, which can be infifinitely 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.

HysteresisLess than 3%
Flow PathFree Flow:① to ②coil energized; Relieving:  ① to ②coil de-energized
Temperature-40 to 120C
FluidsMineral-based or synthetics with lubricating properties at viscosities of
7.4 to 420 cSt (50 to 2000 sus)
Installation RecommendationWhen 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.

Operation Symbol of ITS10-27 Piloted Relief Valve

Operation Symbol of ITS10-27 Piloted Relief Valve

The ITS10-27 blocks flow from① to ② until sufficient pressure is present at ① to open the valve by overcoming the preset-induced spring force. With no current applied, the valve will relieve at±50 psi of the range maximum. Applying current to the coil decreases the induced spring force, thereby reducing the valve setting.


Note


This valve is ideal for hydraulic fan drive applications.
