Caterpillar GP 7I-8136 Hydraulic Control Valve

The Caterpillar GP 7I-8136 is an original Caterpillar GP valve group, a hydraulic control valve assembly used within Cat hydraulic systems. Identified by part number 7I-8136, this GP valve is part of Cat’s GP valve family and is cataloged as an OEM Valve GP in Cat Parts listings, confirming its status as a genuine Cat component. The exact port counts, thread sizes, mounting configuration, and operating pressures depend on installation and machine model, so compatibility should be verified with the Caterpillar parts catalog or through a Cat dealer before replacement. As an OEM GP valve group, it functions within a hydraulic valve bank to support the control of actuators and hydraulic functions in heavy equipment—helps ensure consistent, factory-aligned operation within Cat’s hydraulic architecture.
