PNEUMATIC VALVE POSITIONER is an instrument working on force balanceprinciple to position the Control Valve stem in accordance to a pneumatic signal received from acontroller or manual loading
station, regardless of packing box friction, actuator hysteresis orunbalanced forces on the valve plug. Thus, the positioner ensures a reliable and accurate operationof Control Valve.
