Brief: Explore what sets this solution apart in an easy-to-follow presentation. In this video, we showcase the VUSF-G1/2 hydraulic control valve for excavator hydraulic systems. You'll see how its ball-type structure enables automatic high-pressure selection and logic switching functions. We demonstrate its compact design, rapid response capabilities, and applications in construction machinery like excavators and loaders.
Related Product Features:
  • Automatically selects the higher-pressure input from two circuits for high-pressure priority or logic switching functions.
  • Features a ball-type structure with rapid response and virtually delay-free switching for dynamic load changes.
  • Compact G1/2 threaded straight-through design for easy installation in valve blocks or pipelines.
  • Constructed from high-strength carbon steel with surface rust-proof treatment for durability.
  • Maximum working pressure of 350 bar with excellent resistance to high-pressure impacts.
  • Minimal internal leakage design reduces energy loss and improves overall system efficiency.
  • Widely used in construction machinery load sensing systems, hydraulic motor braking, and pilot control circuits.
  • Suitable for harsh working conditions with long service life and reliable performance.
FAQs:
  • What are the key points of routine maintenance for this hydraulic control valve?
    Keep the hydraulic oil clean and change the filter element regularly. Avoid prolonged use on one side under high pressure differential to prevent accelerated wear. Install dust caps or protective covers, and monitor signal pressure stability during system commissioning. If significant pressure attenuation occurs, disassemble and inspect promptly.
  • What is the warranty period for the VUSF-G1/2 hydraulic control valve?
    We offer a 10-month warranty for the VUSF-G1/2 hydraulic control valve, ensuring reliable performance and customer satisfaction.
  • What applications is this hydraulic control valve suitable for?
    This valve is widely used in construction machinery load sensing systems (such as excavators and loaders), hydraulic motor braking/priority oil supply circuits, pilot control applications, and dual-pump confluence systems.
  • What are the pressure and flow specifications for the VUSF-G1/2 model?
    The VUSF-G1/2 model has a maximum flow rate of 80 L/min, maximum working pressure of 350 bar, and a nominal diameter of 13 mm.
