GB Forged Steel Flanges Gate Valve
Product overview
GB Forged steel flanges gate valve is suitable for small diameter pipeline with pressure of 1.6 ~ 42.0mpa (Class 150 ~ 2500), working temperature of - 29 ~ 425 ℃ (carbon steel) or - 29 ~ 500 ℃ (stainless steel). It is used to cut off or connect the medium in the pipeline. It can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media, and is widely used in oil pipeline 。
Product Features
GB Forged steel flanges gate valve are of Dalian type reduced diameter design. Compared with the cast steel gate valves of the same diameter, the flow rate is slightly smaller, but the pressure and temperature range they bear are higher than those of the cast steel gate valves, the sealing performance is also much better than that of the cast steel gate valves, and the service life is longer. The flow direction of the medium is not limited as other gate valves.
