Product Overview
The A4VG125 hydraulic pump control valve is designed to regulate pressure, displacement, and hydraulic flow control in Rexroth A4VG axial piston pumps used in heavy-duty mobile hydraulic systems. This control valve is a critical component responsible for maintaining stable pump performance and efficient hydraulic operation.
Manufactured for durability and precise hydraulic response, the control valve ensures smooth pump displacement adjustment under varying load conditions. It helps maintain system efficiency and protects hydraulic components from excessive pressure fluctuations.
The valve is commonly used in construction machinery, excavators, road equipment, and heavy industrial hydraulic systems, providing reliable hydraulic pump control and extended equipment service life.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
