Abstract
An actuator for actuating a valve from a first position to a second position includes a housing and a rotatable stem mounted within the housing and restricted from moving axially. The actuator also includes a non-rotatable plunger engaging the stem such that the plunger moves axially in response to rotation of the stem, whereby the valve is actuated from the first position to the second position. The actuator is also provided with a non-rotatable indicator member, which is mounted within the housing and through which the stem extends. The indicator member engages the stem such that the indicator member moves axially in response to rotation of the stem. A viewing window is formed in a wall of the housing such that the indicator member can be seen through the window for indicating the first position and the second position of the valve.
