Hydraulic Power UnitsHydraulic power unit is a hydraulic power assembly that generally includes a motor, hydraulic pump, hydraulic control element, filter, fluid reservoir and other hydraulic components.
Hydraulic Gear MotorsHydraulic gear motors convert hydraulic energy from a hydraulic pump into mechanical energy for rotation, thus, driving the load to work. This gear motor is also used as a hydraulic pump.
Orbit MotorsCycloidal speed reducers convert hydraulic energy to mechanical energy, leading to their wide applicability on agricultural harvesters, seeder, aerial work platform, garbage truck, excavator...
Hydraulic Control ValvesGRH manufactures and provides leak resistant monoblock directional control valves, modular sectional directional control valves, and load-sensitive proportional valves with a rear pressure compensation.
Manifold ValvesStack valves stack multiple hydraulic valves on different levels of a single valve assembly according to the hydraulic principle diagram to achieve a variety of functions through an internal oil passage.
