The Jamesbury RKQ-3 Diaphragm Actuator is a diaphragm-type pneumatic actuator designed to operate Jamesbury valve assemblies by converting compressed air pressure into linear motion to move the valve stem. This model is part of the Jamesbury actuator family and is used in industrial piping systems where Jamesbury equipment is specified for valve actuation. The RKQ-3 provides direct actuation of Jamesbury valves to control flow in process lines that rely on pneumatic valve actuation.
