  • High Temperature Butterfly Valve

    High Temperature Butterfly Valve

    High temperature butterfly valve is a new generation of high temperature butterfly valve developed by MST by introducing foreign advanced technology and combining with Chinese manufacturing process. High temperature butterfly valve is widely used in metallurgy, building materials, chemical industry, power station, glass and other industries in the high temperature gas pipeline. As a high temperature gas medium flow regulation or cut-off device, high temperature butterfly valve can be used with various actuators to form different performance equipment.
  • Non Rising Stem Gate Valve

    Non Rising Stem Gate Valve

    Gate valve is a kind of valve for medium connection and shut- off but not suitable for regulating. Compared with other valves, gate valves have a wider range of combined applications for pressure, service fluid, design pressure and temperature. According to the screw position of the stem, the gate valve can be divided into rising stem gate valves and Non Rising Stem Gate Valve .
  • Flange Globe Valve

    Flange Globe Valve

    Flange globe valve is a kind of globe valve. globe valve is a valve that opens and closes by driving the valve disc by the valve stem. globe valve can be divided into flange globe valve, welded globe valve and threaded globe valve according to different connection modes.
  • Metal seated gate valve

  • What Makes a 4 Inch Natural Gas Ball Valve the Right Choice for Your Gas Pipeline System?

    ​Choosing the right gas valve is essential for ensuring safety, performance, and long-term reliability. A 4 inch Natural Gas Ball Valve is widely used in industrial pipelines, energy stations, gas distribution networks, and high-pressure transmission systems. In daily engineering projects, I often find that selecting the correct valve size and structure directly affects the stability of the entire pipeline.

  • Where are pneumatic butterfly valves used?

    In industrial control, the pneumatic actuator principle structure drives the air source from port A, the gear shaft rotates counterclockwise, and the valve Open the pneumatic actuator principle structure in the industrial control to drive the air source from port B, the gear shaft rotates clockwise, and the valve closes.

  • What Makes an On Off Butterfly Valve Essential in Modern Flow Control?

    On Off Butterfly Valve systems are vital components in piping and process industries where quick isolation and flow control are required. These valves serve as reliable shut‑off devices that operate in either fully open or fully closed states, making them ideal for isolation duties rather than gradual flow regulation.

  • Features of Soft Seal Butterfly Valve

    With the increase of the reverse medium pressure, when the unit positive pressure between the soft-sealed butterfly valve plate and the soft-sealed butterfly valve seat is less than the medium pressure, the deformation stored in the spring of the adjusting ring after loading can compensate the soft-sealed butterfly valve plate and the soft-sealed butterfly valve seat. The tight pressure on the sealing surface of the sealing butterfly valve seat plays an automatic compensation role.
