A6VM HD1D Hydraulic Pump Proportional Control Valve High Pressure For Large Harvester
A6VM HD1D Hydraulic Pump Proportional Control Valve High Pressure For Large Harvester
Product Introduction
The A6VM HD1D pump control valve is a pilot hydraulic proportional control valve for A6VM bent - axis piston pumps. Adopting HD hydraulic proportional control tech, it enables stepless displacement adjustment from 0 to Vgmax. Integrating pressure cut - off and flow regulation, it has a pilot control pressure of 3 - 10 bar and main pressure suitable for 50 - 350 bar systems. It fits closed/open circuits, offering stable pressure and flow control for pumps in high - pressure conditions like construction machinery.
Product Summary
Control valves are core control components in hydraulic systems, responsible for regulating the direction, pressure, and flow of oil to ensure precise operation of actuators. They mainly include directional, pressure, and flow control valves, featuring fast response, high reliability, and good adjustment accuracy. Widely used in construction machinery, agricultural equipment, and industrial automation, they are key parts ensuring the safe and stable operation of hydraulic systems.

Product Application
This pump control valve is mainly suitable for construction machinery (crawler cranes, excavator travel mechanisms), agricultural machinery (large harvesters, tractor hydraulic systems), mining machinery (drill rigs, roadheader power circuits), port machinery (container crane luffing mechanisms) and industrial hydraulic stations. It is especially ideal for hydrostatic transmission systems requiring precise speed/torque control, high - pressure heavy loads and complex working conditions to ensure efficient and stable equipment operation.
Product Advantages
This control valve features linear control performance with fast response (≤100ms), suitable for high - pressure and high - frequency conditions. The pilot hydraulic control ensures safety, reliability, strong oil contamination resistance and low maintenance cost. Its integrated design is compact for easy installation and compatible with all A6VM pump models. With adjustable pressure setting of 50 - 350 bar, rated 350 bar and peak 400 bar, it resists impact and suits heavy loads. Made of ductile iron, it is wear - resistant and corrosion - resistant, extending the pump unit's service life.
