Reversing Valve

Reversing Valve is a control valve that switches the flow path of the medium by changing the position of the valve core inside the valve body. It can realize the on/off, directional, diversion or merging of fluid in the pipeline, and has the characteristics of flexible operation and fast response. It is the core component of the fluid control system.Widely used in industries such as hydraulic and pneumatic systems, petrochemicals, engineering machinery, metallurgy, water treatment, etc., it is installed on equipment such as pump stations, hydraulic cylinders, pneumatic actuators, and conveying pipelines to control the direction of motion of actuator components and adapt to the process switching and working condition adjustment of automated production lines.

Common Types

  • Electromagnetic directional valve: driven by electromagnetic coil, fast response speed, suitable for remote automatic control
  • Manual directional valve: driven by hand or lever, with a simple and reliable structure, suitable for small equipment or manual operation scenarios
  • Hydraulic directional valve: driven by hydraulic oil, with high thrust, suitable for high-pressure and high flow hydraulic systems
  • Pneumatic directional valve: driven by compressed air, with good explosion-proof performance, suitable for flammable and explosive working conditions

Structural Advantages & Corresponding Benefits

  1. Precision wear-resistant valve core structure

  • Special point: The valve core is made of stainless steel and forged as a whole, with a ceramic wear-resistant coating sprayed on the surface. The gap between the valve core and the valve sleeve is controlled within 5 μ m.
  • Result:There is no lag in the reversing process, the wear and corrosion resistance is improved by 80%, the sealing performance is stable, and it is suitable for high-frequency reversing conditions.

  1. Integrated pilot control structure

  • Special point: Equipped with a built-in micro pilot valve and pressure differential control design, no additional control of the oil circuit is required.
  • Result: The commutation response time has been shortened to 0.05 seconds, and stable operation can also be achieved under low pressure conditions, simplifying the system pipeline layout.
