ITS10-26 Piloted Relief Valve

Name: ITS10-26 Piloted Relief Valve
Brand: Wuhu Inno Hydraulic Technology Co., Ltd.

A screw-in, cartridge-style, pilot-operated, spool-type hydraulic 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 useas a pressure limiting device in demanding applications.

Specifications of ITS10-26 Piloted Relief Valve

Operating Pressure	240 bar (3500 psi)
Maximum Control Current	1.10 A for 12 VDC coil; 0.55 A for 24 VDC coil
Relief Pressure Range from Zero to Maximum Control Current	A: 6.9 to 207 bar (100 to 3000 psi); B: 6.9 to 159 bar (100 to 2300 psi); C: 6.9 to 117 bar (100 to 1700 psi)
Rated Flow	94.6 lpm (25 gpm), DP=13.1 bar (190 psi), Cartridge only, ① to② coil de-energized
Maximum Pilot pressure	0.76 lpm (0.2 gpm)
Hysteresis	Less than 3%
Flow Path	Free Flow: ① to② coil de-energized; Relieving:① to ②coil energized
Temperature	-40 to 120°C with standard Buna N seals
Fluids	Mineral-based or synthetics with lubricating properties at viscosities of 7.4 to 420 cSt (50 to 2000 sus)
Installation Recommendation	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.
Cavity	IVC10-2; See page 275

Operation Symbol of ITS10-26 Piloted Relief Valve

The ITS10-26 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. With no current applied to the solenoid, the valve will relieve at approximately 100 psi. The optional manual override 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 is required to prevent the system from becoming over-pressurized.
