Hydraulic Valves

Hydraulic Valves

Overview

Hydraulic control valves are the brain of a hydraulic system, controlling pressure, flow and direction to start, stop, regulate, reverse and protect actuators. Our valves cover pressure, flow and directional control valves, proportional valves and cartridge valves, with brands including Rexroth, Parker, Yuken and Huade.

Features

  • Valve body made of high-strength cast iron or forged steel, pressure-resistant and non-deforming
  • Quenched alloy steel spool with chrome plating for long wear life
  • Solenoid directional valves with DC 24 V or AC 220 V coils, IP65 protection
  • Proportional valves for precise position, speed and pressure control with PLC

Applications

Excavator hydraulic systems, loader hydraulic systems, road-roller vibration systems, coal-machinery hydraulic systems and retrofit/repair of industrial hydraulic equipment.

Key Advantages

Complete brand coverage with genuine products; ample stock of common spools and coils; hydraulic system design and fault-diagnosis technical support.
