Able to work in the place without electricity and gas, and at the same time save energy, the pressure setting value can be adjusted at will during operation. The use of fast-opening flow characteristics, sensitive action, good sealing performance, it is widely used in petroleum, chemical, electric power, metallurgy, food, textiles, machinery manufacturing and residential buildings and other industrial equipment in a variety of gases, liquids and steam media to reduce pressure, stabilize the pressure (for the valve after the adjustment), or pressure relief, pressure (for the valve before the adjustment) of the automatic control. Attached condenser can be used at a temperature of < 350 ℃.
