• 1 - Actuated DoubleDisc

    The all stainless steel actuator for the Doubledisc valve mounts quickly on the stem housing of the valve. A set screw allows removal in seconds. The disc stem of the air actuated valve terminates in a square shaft. This fits into a brass coupling which, in turn, connects to the pinion gear. Two brass racks govern the 180° rotation as the air or springs control the two pistons.
