Z41H forged steel flange gate valve
Z11H forged steel internal thread gate valve
Steam forged steel gate valveProduct Introduction
Forged steel gate valves are all gate valves made of forged materials, collectively known as forged steel gate valves. Forged materials include A105, F11, F5, 304, 304L, 316, 316L, etc. The commonly referred to forged steel gate valve in China usually refers to small-diameter forged steel gate valves, with a diameter range of DN10~DN50; Pressure range: National standard PN16~PN320, American standard: Class 150~2500, can be produced and processed in American standard or national standard sizes. Forged steel gate valves with diameters exceeding DN50 need to be customized.
Steam forged steel gate valveProduct Features
Most forged steel gate valves are designed with Dalian style reduced diameter. Compared with cast steel gate valves of the same diameter, the flow rate is slightly smaller, but the pressure and temperature range they can withstand are higher. The sealing performance is also much better than cast steel gate valves, and the service life is longer. The direction of medium flow is not restricted like other gate valves.
Steam forged steel gate valveapplication
Forged Steel Gate ValveSuitable for small-diameter pipelines with Class 150-2500 and working temperatures of -29~425 ℃ (carbon steel) or -29~500 ℃ (stainless steel), used to cut off or connect media in pipelines. Different materials are selected and can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc. The hydrophobic valve (Shanghai) Co., Ltd. mainly applies it to steam pipelines.
