Abstract
There is disclosed a pilot valve which controls the flow of a control fluid to and from a fluid-operated actuator, and which comprises an inlet to admit the control fluid to a chamber thereof, a port connecting the chamber with the actuator, a passageway connecting the chamber with a vent port, and a ball which is shifted between a set position closing the passageway so that control fluid is admitted from the inlet to the actuator and a tripped position closing the inlet so that control fluid is exhausted from the actuator out the vent port.
