      • Ordering Process

      Low temperature gate valve is suitable for methane, liquid natural gas, hexene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen, liquid hydrogen and other low temperature medium.

      Characteristic

      1. In order to prevent abnormal pressure in the middle cavity, pressure relief holes are installed on the inlet side of the gate.

      2. Determine the top length of the valve cover according to the working temperature of the valve to ensure the reliable seal of the stem packing.

      3. According to working temperature, materials such as stuffing, gaskets and so on are selected reasonably.

      4. Strictly control the mechanical properties of materials such as chemical composition and low temperature impact toughness.

      5. Adopt a variety of pipe flange standards and sealing face type, suitable for all kinds of engineering needs.
