Rotational displacement of the shaft clockwise causes the first seal to seal off the source of fluid pressure from the valve chamber, while allowing for fluid discharge through the drain port. Rotational displacement of the shaft in a second, opposed direction connects the pressure-operated device ...
A fluid pressure source is coupled via an input port to an inner end of the bore which includes a valve chamber. An output port coupled to a pressure-operated device is also disposed in the housing and is connected to the valve chamber, as is a drain port. Attached to the shaft's ...
