What is a gate valve

Gate valve in the pipeline can only be used for full open and full closed blocking, can not be adjusted and throttled.Gate valve is a kind of valve with a wide range of use. It is usually used for intercepting devices with diameter DN≥50mm, and sometimes also for blocking devices with small diameters. Gate valve is used as the cut-off medium, and the whole smooth and longitudinal penetration is smooth when fully opened, and the pressure loss of medium operation is minimal.Gate valves are normally used for operating conditions in which the gate is not always open or closed and the gate is kept fully open or fully closed.Not used for regulating or throttling.For high speed moving media, gate vibration can be caused by partial opening of the gate, which may damage the sealing surface of the gate and seat, while throttling may cause the gate to be eroded by the medium.

What media is 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 used for water, steam, oil products, nitric acid, acetic acid, oxidizing medium, urea and other media.
