High temperature and high pressure power station valve is a kind of high quality and high performance valve designed by our company for high temperature and high pressure pipeline in order to meet the needs of customers and society. It fully utilizes modern raw materials and processing technology. It is designed and manufactured in accordance with internationally recognized standards and quality assurance requirements. It is manufactured and processed in standard workshop certified by ISO, 9001 and TS. The valve body and cover adopt pressure self-tightening sealing structure. The higher the pressure, the better the sealing performance, so as to ensure the sealing at the joint of the body cover. The sealing pairs are made of Stellite Co-based cemented carbide with different hardness, high hardness, good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life. The upper sealing surface is made of austenitic stainless steel or cemented carbide surfacing. The sealing is reliable and corrosion-resistant. The replacement of filler can be carried out without stopping the operation of the system. The valve stem has good corrosion resistance and abrasion resistance after quenching and tempering and surface nitriding treatment. The operation mode can be manual, gear transmission, electric, or pneumatic, etc.
