Product Usage
Forged steel gate valve is suitable for pressure 1.6~42.0MPa (Class150~2500), the working temperature -29~425℃(cabon steel) or -29~500℃(stainless steel) of small diameter pipe road, used to truncate or through line in the medium, choose different material, can be respectively suitable for water, steam, oil, nitric acid, oxidizing medium, urea, and other media, In the path of the oil pipeline more application.
Product Features
Forged steel gate valve are designed as reducing, port and compared with the diameter of the cast steel gate valves flow to be smaller, but the pressure and temperature range is higher than cast steel valve, sealing performance is much better than cast steel gate valves, longer life, medium flow direction as well as other gate valve is not restricted.
