Rotork Electro Pneumatic Valve Positioner also referred to as: pneumatic valve positioner is the primary accent of the management valve. It's often used along side the pneumatic management valve. It receives the output sign of the regulator, after which makes use of valve positioner output sign to regulate the pneumatic management valve. After the valve is actuated, the displacement of the valve stem is fed again to the valve positioner by way of the mechanical machine, and the valve place standing is transmitted to the higher system by way of electrical alerts.
