Dec 4, 2013 — Now the final valve travel direction will depend on the actuator action....air to close or air to open. If a direct acting positioner is used on an air to close actuator then it means as you increase 4-20mA signal, the valve will be moving towards 100% close position. To change action of positioner ...

valve plug. In Figure 3.6, a three-way valve body with a balanced valve plug is shown with the cylindrical valve plug in the mid- travel position. This position opens the bottom common port to both the right-hand port and left-hand port. The construction can be used for throttling mid-travel position control of either.
