A control valve system having 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. A first plurality of valves are disposed within the first passage, each being selectively actuated to close, open, or partially open the first passage. A second plurality of valves are disposed within the second passage, each being selectively actuated to close, open, or partially open the second passage. A plurality of reset members are selectively engageable with the first plurality of valves and are operable to actuate the first plurality of valves when a pressure is applied to the plurality of reset members. The plurality of reset members each have an anti-tiedown stem extending therefrom to prevent operation of the control valve system if any of the plurality of reset members is tied down.

Double valve with anti-tiedown capability

A control valve system has two valve trains each of which has a series of valves which dynamically move between a deactuated position and an actuated position. An inlet of the valve system is connected to an outlet of the valve system when all of the valves are actuated and the outlet of the valve system is connected to an exhaust when all of the valves are deactuated. Each valve train includes a solenoid valve which when actuated moves the remaining valve members to their actuated position. The various valves of each valve train are interconnected with the valve of the other valve train such that actuation of all of the valves in a substantially simultaneous manner will connect the inlet of the valve system to the outlet of the valve system and deactuation of all of the valves in a substantially simultaneous manner will connect the outlet to the exhaust. The valve system monitors the dynamic movement of the valve members during its operation will move to a locked out condition when any valve is in a deactuated position and when one other valve is in an actuated position. In the locked out condition, the outlet of the valve system is corrected to the exhaust. The valve system will remain in this locker out condition until a resetting operation is performed. During a reset operation, the valve system can not actuate one of the valve trains because one of the valve trains is depressurized during the reset operation.

In the locked out condition, the outlet of the valve system is connected to the exhaust. In one embodiment, the valve system will remain in this locked out condition until a resetting operation is performed. In an additional embodiment, the valve system will automatically reset itself
