Valve Positoner

Valve Positioner is a precision positioning device for valves, which receives control signals and accurately positions the valve core to the specified opening, compensates for valve deviation, and improves adjustment accuracy.
2. Purpose
Widely used in industries such as petrochemicals, power, metallurgy, and municipal engineering, it is equipped with regulating valves, butterfly valves, and ball valves to achieve precise control of valve opening and adapt to fluid flow and pressure fine adjustment conditions.

Common Types

  • Pneumatic valve positioner: Pneumatic drive, fast response, suitable for chemical explosion-proof working conditions
  • Electric valve positioner: motor-driven, precise digital display, suitable for automation control scenarios
  • Intelligent valve positioner: with communication function, capable of remote monitoring/debugging, compatible with intelligent industrial control systems
  • Intrinsic safety valve positioner: high explosion-proof rating, suitable for flammable and explosive hazardous environments

Structural Advantages & Corresponding Benefits

  1. High precision feedback positioning structure

  • Special point: Built in displacement sensor, real-time feedback of valve core position, closed-loop automatic compensation for deviation
  • Result:High precision in opening adjustment, no lag, stable flow and pressure control, suitable for refined processes

  1. Anti interference sealing structure

  • Special point: The shell is waterproof, dustproof, and explosion-proof, the internal circuit is resistant to electromagnetic interference, and the gas/circuit is independently sealed
  • Result: Suitable for harsh industrial conditions, stable operation, strong protection, and long service life
