The Comodity Cast Steel Gate Valve is mainly composed of valve body, valve cover, valve wedge, valve seat and valve stem. The two sealing surfaces are wedge-shaped gate valves. The purpose of the wedge is to improve the auxiliary seal load, to achieve both high medium pressure sealing and low medium pressure sealing. The valve body of the wedge valve is provided with a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
Compared with other valve products, High Temperature and High Pressure Slab Gate Valve is characterized by high temperature and high pressure. Among them, grooved flange is designed as a unique self-tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The high-temperature and high-pressure gate valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the sealing surface of the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
The valve disc of the Cryogenic Swing Check Valve adopts a cantilevered swing structure, combined with precisely machined valve seat sealing surfaces, to achieve rapid response and reliable sealing, effectively preventing the reverse flow of the medium. The overall design of the valve complies with international standards such as BS 6364 and ISO 28921, and is suitable for low-temperature conditions in air separation plants, liquefied natural gas storage and transportation, and the chemical industry.
