Variable pressure control device |
摘要 |
<p>A control valve system having a housing defining an inlet, an outlet, and an exhaust. A first passage extends between the inlet and the outlet and a second passage extends between the outlet and the exhaust. The control valve system includes a first valve disposed within the first passage. The first valve is movable between a closed position and an opened position. Similarly, the control valve system includes a second valve disposed within the second passage. The second valve is movable between a closed position and an opened position. Furthermore, the control valve system includes a regulator circuit operably coupled to the housing, which outputs a pilot pressure in response to an inlet pressure. An actuating member is slidably disposed within the housing and moveable in response to a pressure differential between the outlet and the pilot pressure. The actuating member independently actuates the first valve and the second valve to provide a quick pressure and exhaust feature. <IMAGE></p> |
