The gate valve can only be used for full opening and full closing in the pipeline, and cannot be used for adjustment and throttling. Gate valve is a kind of valve with a wide range of use. Generally, it is used for blocking devices with a diameter of DN ≥ 50mm. Sometimes a gate valve is also used for blocking devices with small diameters. The gate valve is used as cut-off the medium, the pressure loss of medium operation is the smallest at this time. Gate valves are usually used in conditions that do not need to be opened and closed frequently and keep the gate fully open or fully closed. Not suitable for regulation or throttling use. For high-speed moving medium, the gate can cause vibration of the gate when it is partially opened, and the vibration may damage the sealing surface of the gate and the valve seat, and the throttling will cause the gate to be eroded by the medium.
What medium is the gate valve suitable for?
Gate valve is suitable for Class150 ~ 2500, working temperature -29 ~ 425 ℃ (carbon steel) or -29 ~ 500 ℃ (stainless steel) pipeline, used to cut off or connect the medium in the pipeline, choose different materials, can be respectively Suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other medium.
