The failure modes in the control valve actuator is achieved by combining direct acting or reverse acting actuator and direct acting or reverse acting valve body. The selection of valve actuator and valve body is done in such a way to …
Introduction The Control Valves consist of the single-seated Angle Valve and Pneumatic Actuator.The process medium flows through the valve in the direction indicated by the arrow. The position of the plug (3) is changed by the signal pressure acting on the diaphragm in the actuator (8).The plug stem (6) and plug are connected to the actuator stem (8.1) by the stem connector (7). …
