ABSTRACT:
A pilot valve for connecting a source of fluid under pressure to an actuator where the pilot valve may be connected to the actuator in any of 360.degree. of rotation so that the fluid connections may be made from any desired direction. Further disclosed is a coupling adapter joining the pilot valve to the actuator with passages so arranged in the adapter that 180.degree. rotation of the coupling adapter reverses the fluid flow connections between the pilot valve and the actuator simultaneously exposing indicia indicating the condition. Still further disclosed is a spring return manual override that is slotted to enable operation by a coin and has a mating slot in the pilot valve body allowing locking in the override position by insertion of a coin or similar device. A ball valve actuator is described as an actuator device.
