Chrome-molybdenum steel stop valve
Other Products
I. Introduction:
All main parts of the chromium-molybdenum steel gate valve, such as the valve body, bonnet, disc and valve stem, are made of chromium-molybdenum steel or chromium-molybdenum-vanadium steel. These materials have excellent hydrogen corrosion resistance and good high-temperature strength, making them the preferred choice for high-temperature and high-pressure working conditions. This product features a simple structure, reliable operation, low failure rate and convenient maintenance, so it is widely used in power plants such as thermal power stations, hydropower stations and nuclear power stations. The chromium-molybdenum steel gate valve applies downward pressure to the sealing surface through the torque of the valve stem. Relying on the pressure of the valve stem, the sealing surface of the disc closely fits with the sealing surface of the valve seat to block the inflow of the medium or adjust the flow rate of the medium. Therefore, this type of valve is very suitable for pipelines in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer and power industries, serving as a shut-off, regulation and throttling device.
II. Product Features:
① The product meets the requirements of advanced domestic and international standards, with a reasonable structure, reliable sealing, excellent performance and beautiful appearance.
② The product has a complete range of material types. The packing and gaskets can be reasonably selected according to actual working conditions or user requirements, making it applicable to various pressure, temperature and medium working conditions.
③ The pressure-bearing parts of the high-temperature valve are made of high-quality heat-resistant alloy steel, and the sealing surface is made of Stellite cobalt-based hard alloy, ensuring reliable sealing, stable performance and long service life.
④ The valve stem of the high-temperature valve is made of heat-resistant alloy steel, which undergoes tempering and surface oxidation treatment, giving it excellent comprehensive mechanical properties, corrosion resistance and scratch resistance.
⑤ The product adopts an inverted sealing structure, allowing maintenance and replacement of sealing packing without shutting down the equipment.
⑥ It can adopt various piping flange standards such as ANSI, GB, JB, HG, SH and flange sealing surface types to meet various engineering needs and user requirements.
⑦ Integrated intelligent electric devices of imported series such as IQ, 2SA35, SMC, RA and STK can be selected according to user requirements. These devices have the characteristics of complete functions, high precision and compatibility with program-controlled computers.
