What Is A Reverse Acting Controller. The choice of valve action is dictated by safety considerations. All control systems are programmable (usually marked dir/rev) which allows the controller to be switched from direct acting to reverse acting or vice versa. In direct acting mode, an increase in control signal pressure causes and increase in. The controller, positioner and the control valve act in the following ways: In a direct acting actuator, an increase in the pneumatic pressure applied to the diaphragm extends the valve stem (for a normally seated valve this will close the valve and is called ‘air to close’). In this article, we review the operations of a direct acting and a reverse acting actuator and compare. Direct acting and reverse acting provide two methods by which actuators control a valve. A positioner can operate in either direct or reverse acting mode. A reverse acting controller is one whose output tends to decrease as the measurement signal increases. As the process variable (flow or pressure) increases. Reverse acting control valve loop.
