发明名称 Shut-off valve having two seats providing pressure equalization
摘要 A shut-off valve that has particular application for opening and closing a compressed hydrogen storage tank. In one embodiment, the valve includes two valve sealing members where one side of one valve sealing member is on the high pressure side of the valve and an opposing side of the other valve sealing member is on the high pressure side of the valve. Therefore, the pressure applied to the two valve sealing members offset each other so that less force is required to open the valve against the high pressure.
