Hydraulic Pump Control Valve

Product Introduction

This integrated control valve for Rexroth A11VO95/130/145 swash plate axial piston pumps integrates constant power (LR), pressure cut - off, load - sensing (LS) and differential pressure compensation. Suitable for open circuits, it has a rated pressure of 350 bar and peak pressure of 400 bar. Adopting pilot hydraulic control, it enables stepless displacement adjustment from 0 to Vgmax, accurately matching pump operating conditions and providing stable pressure and flow for mobile machinery hydraulic systems, suitable for heavy - duty operations.

Product Summary

Product Parameters

Product Application

This pump control valve is mainly suitable for construction machinery (excavators, crawler cranes, concrete pump trucks), mining machinery (roadheaders, mining dump trucks), agricultural machinery (large tractors, combine harvesters) and forestry machinery (loggers). It is especially ideal for open - loop, high - pressure heavy - duty and variable - condition hydrostatic transmission systems to ensure efficient and stable equipment operation.

Product Advantages

This control valve features constant power + load - sensing dual control, with a response time of ≤120ms and low energy consumption. The integrated design reduces pipeline connections, lowering leakage and vibration risks. It is 100% compatible with original A11VO pumps for easy installation. It has strong anti - pollution ability and is suitable for ISO 46 anti - wear hydraulic oil. The valve body is wear - resistant and corrosion - resistant, and the alloy spring has a long fatigue life with low maintenance cost.
