The STEVI-POS P20 is a digital electro-pneumatic positioner designed for single-acting pneumatic rotary actuators. It converts a 4–20 mA control signal into valve angle and modulates actuator air pressure via an integrated pneumatic module. Position feedback is provided by a non-contact Hall effect magnetic sensor, eliminating mechanical wear in the measurement system.
The positioner compares valve angle to setpoint and adjusts actuator pressure within a defined deadband. Deadband can be automatic or fixed at 0.5%, 1%, or 3%. The tight-closing function fully vents the actuator when the setpoint exceeds configured limits, ensuring available closing force is applied.
Suitable for rotary control valves in:
Available as 2-wire 4–20 mA or with passive analog position output 4–20 mA, 9–32 V. Optional dual gauge set 0–10 bar for supply and working pressure monitoring.
What happens on signal or air loss?
The valve is vented in accordance with the actuator’s fail action.
What should be checked before selection?
Rotation angle, actuator type, air pressure, G/NPT connection, feedback requirements, and installation position.
