Abstract
A gas control valve has a valve housing, a gas flowpath, a piston, a valve seat, a valve body, an actuating chamber, and a stack of Belleville washers. The valve housing has a gas inlet, a gas outlet, and a control fluid inlet. The gas flowpath runs from the gas inlet to the gas outlet. The piston reciprocates away from and towards a normal position. The valve body is coupled to the piston and is adapted to selectively seat on the valve seat to open and shut the gas flowpath. The actuating chamber communicates with the control fluid inlet. The washer stack is under compression to bias the piston in the normal position. The piston is responsive to fluid pressure in the actuating chamber and the washer stack so that the valve may be selectively opened and closed by sequentially increasing and decreasing pressure in the actuating chamber.
