Structural advantages and characteristics
*The product is designed and manufactured according to API standards, with reliable sealing, excellent performance, and can be used in conjunction with imported equipment.
*The sealing surface of the gate and valve seat above 600Lb is made of Stellite cobalt based hard alloy welding, which has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance, and long service life.
*The valve stem has undergone quenching and surface nitriding treatment, providing excellent corrosion resistance and abrasion resistance.
*Adopting a wedge-shaped elastic gate structure, rolling bearings are installed on medium and large diameters for easy opening and closing.
*The valve body material variety is complete, and the packing and gasket are reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.
*The 1500Lb and 2500Lb chambers adopt a pressure self tightening sealing structure. The sealing performance increases with the increase of internal pressure, and the reliability is high.
*The reverse seal is made by connecting the sealing seat with stainless steel threads or welding austenitic stainless steel on the body. The reverse seal is reliable, and the replacement and maintenance of the packing can be carried out without stopping the machine, which is convenient, fast and does not affect the operation of the system.
