The gas pressure reducing valve uses the opening of the opening and closing parts in the valve body to adjust the flow of the medium and reduce the pressure of the medium. At the same time, the opening of the opening and closing parts is adjusted by the pressure behind the valve. The pressure behind the valve is maintained within a certain range, and cooling water is sprayed into the valve body or behind the valve to reduce the temperature of the medium. This type of valve is called a pressure reducing and temperature reducing valve.
