Flexible Installation Hydraulic Control Valve VUSF-G1/2 For Excavator Hydraulic System Control

Hydraulic Control Valve Introduction

The VUSF-G1/2 is a high-performance hydraulic control valve with a ball-type structure. It automatically selects the higher-pressure input circuit from two input circuits and outputs it to a common outlet, enabling high-pressure priority or logic switching functions. The valve body is typically made of high-strength carbon steel, featuring a compact structure, rapid response, minimal internal leakage, and resistance to high-pressure impacts. It is widely used in load sensing systems of construction machinery (such as excavators and loaders), hydraulic motor braking/priority oil supply circuits, pilot control, and dual-pump confluence applications.

In addition to the VUSF series hydraulic control valves, we also offer a variety of hydraulic valves such as hydraulic directional valves and two-way balance valves, as well as products such as the VBSO-DE-*G-G/M two-way balance valve and the SO-K*-B two-way hydraulic lock. Welcome to inquire.

Hydraulic Control Valve Parameters

Hydraulic Control Valve Application

• Automatic High-Pressure Priority Selection: No external control signal is required. The steel ball structure responds instantly to pressure differences, automatically selecting the highest-pressure oil circuit to ensure precise and reliable load sensing or logic control.
• Extremely Fast Response: Switching is virtually delay-free, suitable for engineering machinery systems with frequent dynamic load changes (such as excavators and loaders).
• Compact Structure and Easy Installation: G1/2 threaded straight-through design, small size, and light weight, easily integrated into valve blocks or pipelines, saving space.
• High Pressure and High Impact Resistance: Maximum working pressure 350 bar. The valve body is made of high-strength carbon steel with surface rust-proof treatment, suitable for harsh working conditions and long service life.
• Minimally Low Internal Leakage: Excellent sealing performance reduces energy loss and improves system efficiency.

FAQ

Q: What are the key points of routine maintenance?

A: Keep the oil clean, change the filter element regularly, avoid prolonged use on one side under high pressure differential (accelerates wear on one side); install dust caps/protective covers; monitor the stability of the signal pressure during system commissioning, and disassemble and inspect promptly if there is significant attenuation.

Q: What is the warranty period?

A: We offer a 10 months warranty.
