High Temperature And High Pressure Gate Valve

  High temperature and high pressure gate valve, also known as power station special valve, is mainly used in the pipeline of various systems of thermal power station, cut off or connect the pipeline medium.

  It is mainly applicable to the medium: water, steam and other non-corrosive media. Due to the special performance and technical characteristics and working conditions, the product has also formed the characteristics that can not be replaced by other products, and it is widely used in thermal power plants, petrochemical, metallurgy and other high temperature and high pressure water, steam, oil, superheated steam pipelines. This type of valve should generally be installed horizontally in the pipeline. The valves are designed to withstand extreme temperatures and high pressures, ensuring maximum safety and reliability.

  Main design specifications for high temperature and high pressure gate valves

  Design and manufacture GB/T12234 ASMEB16.34

  Structure length JB/T3595

  Interface connection size JB/T3595 GB/T12224

  Inspection and test JB/T3595 MSS SP61

  Pressure and temperature standard JB/T3595 ANSI B16.34

  Design Principles

  First, the valves are designed to be able to handle extreme temperatures and pressures without compromising performance. The valves are made of high-quality materials that can withstand high temperatures and pressures, such as stainless steel, alloy steel, and carbon steel.

  Second, the valves are designed to be easy to operate and maintain. They are typically equipped with handwheels or actuators that allow for easy opening and closing, and they are designed to be easy to repair and maintain.

  Structure advantages

  1. Pressure self-tightening seal is adopted, and both ends of the valve body branch pipe are welded. The higher the pressure of the inner cavity, the better the sealing performance, with a certain high temperature and pressure resistance, in the actual use of the welding connection, the safety will be higher.

  2. Valve seat and valve flap sealing surface are made of cobalt-based cemented carbide plasma spray welding, and the valve stem is treated by corrosion resistance nitriding, with good corrosion resistance, high hardness sealing hardness, wear resistance and abrasion resistance. Good sealing performance ensures that the valve is very easy to open and close, so that the valve life in the actual use of the process is very long.

  3. The valve can be operated remotely. Now in the use of high temperature and high pressure gate valve, its operation is very simple, whether it is opened or closed, it can be controlled by the electric device, the electric device also includes a lot of spare parts, remote operation can save labor costs, and the safety of the entire management is also very high.

  Overall, high temperature and high-pressure gate valves are essential components in many industrial processes. Their specialized design makes them well-suited for use in high-pressure and high-temperature applications, ensuring maximum safety and reliability. With their strong performance and ease of use, they are an excellent choice for industries that require reliable and durable control valves.
