Single Acting Smart Control Valve Positioner Control Systems Explosion Proof ExdC45GY-RSA

Smart valve positioner, flameproof explosion-proof Exd, angular stroke, single acting, failsafe, stainless steel corrosion-resistant

A valve positioner is a device that adjusts the valve actuator’s position based on a control signal. These positioners are best used in control applications because of their precision.

Valve positioners are usually mounted on the yolk or top casing of a pneumatic actuator for linear control valves, or near the end of the shaft for rotary control valves. For either configuration, the positioner is connected mechanically to the valve stem or valve shaft. This allows for the valve’s position to be compared with the position requested by the controller. When a control signal differs from the valve actuator’s position, the valve positioner sends the necessary feedback to move the actuator until the correct position is reached.
