Forged Steel Flange Gate Valve
Main Material：The Valve Body, Gate Plate, And Valve Stem Are All Made Of Integral Forged Steel
Nominal Diameter：DN15 - DN300
Nominal Pressure：PN16 - PN100
Temperature Range：- 29℃ - 425℃
- The forging process has excellent high-pressure anti explosion performance. The valve body adopts integral forging (rather than casting), with fine metal grains and no pores or sand holes. Its tensile strength is more than 30% higher than cast steel, and it can withstand PN100MPa ultra-high pressure impact. It is suitable for extreme high-pressure scenarios such as oil and gas wellheads, high-pressure pipelines, and supercritical fluid systems. Its anti explosion safety is far superior to ordinary cast steel gate valves.
- The wedge ram is reliably sealed with an elastic wedge ram, which compensates the temperature difference and processing error through the medium Pressure and the elastic deformation of the ram. The hard sealing surface is closely fitted, the leakage class reaches ANSI Class V. The sealing performance is stable under high temperature and high pressure, which can effectively block the reverse flow of high-pressure medium, and is more suitable for the working condition of high pressure difference than the horizontal ram.
- The Stellite alloy, which is temperature resistant and wear-resistant, is suitable for extreme media sealing surface welding. Its hardness reaches HRC 58 or above, and it can resist the erosion and wear of high-pressure sand containing oil and gas, and high-temperature steam. Its service life is 3-5 times longer than that of ordinary gate valves; High temperature alloy Material can work stably at 650 ℃ for a long time. Low temperature alloy is suitable for -196 ℃ liquid natural gas, covering extreme media in a wide temperature range.
- The safety valve stem for structural optimization operation is designed with an open stem, and the opening is visually visible to avoid misoperation; Equipped with rolling bearings for medium and large diameters, the opening and closing torque is reduced by 40%, making manual operation effortless; Equipped with a valve stem anti spray structure (compliant with API 600) to prevent high-pressure media from ejecting the valve stem; Widely used in high-pressure industrial systems such as petroleum extraction, coal chemical industry, nuclear power, and high-pressure hydraulic systems.
