Designed specifically for deep-cold media such as LNG and liquid oxygen, this valve features an austenitic stainless steel body that undergoes special deep-cold treatment to ensure reliable sealing and operational performance under extreme conditions of -196℃. The valve stem adopts an extended neck design and is equipped with a vacuum insulation structure, effectively blocking the transmission of cold energy. The valve can be equipped with either a flat seal or a conical seal structure, allowing for selection based on different pressure ratings, and is suitable for precise flow control in liquefied natural gas storage and transportation, air separation equipment, and low-temperature chemical systems.
The Rotary Ball Valve adopts advanced ball rotation sealing technology and is specially designed for harsh working conditions. It is suitable for the control of high-pressure, high-temperature and corrosive media in industries such as petroleum, chemical engineering, natural gas, and power. Its unique rotating valve seat structure effectively reduces friction and wear, ensuring more durable sealing performance and easier operation. The valve body is made of high-quality stainless steel, carbon steel or special alloy materials, and is precisely processed and hardened to ensure long-term stable operation. It supports various driving methods such as manual, pneumatic, and electric, meeting different automation requirements and is an ideal choice for industrial pipeline fluid control.
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.
