High temperature and high pressure power station valve is our company in order to meet the needs of customers and society, specially designed for high temperature and high pressure pipeline design of a kind of high quality, high performance valve, filling the use of modern raw materials and processing technology, completely in accordance with the internationally recognized standards and quality assurance requirements to design and manufacture, through ISO, 9001 and TS certified standard workshop manufacturing and processing. The valve body and valve cover adopts the pressure self-tightening sealing structure, the higher the pressure, the better the sealing performance, to ensure the sealing of the body cover connection, the sealing pair are made of different hardness of Stellite cobalt base hard alloy surfacing, high hardness, wear resistance, high temperature resistance, corrosion resistance, abrasion resistance, long service life. The sealing surface is made of austenitic stainless steel or hard alloy surfacing, which is reliable and corrosion resistant. The replacement of packing can be carried out without stopping the machine, without affecting the operation of the system. The valve stem has good corrosion resistance and abrasion resistance after quenching and conditioning and surface nitriding treatment. The operation mode can be manual, gear drive, electric, pneumatic, etc. ​
