QP41M (F) one-piece stainless steel high-temperature sewage valve I. Product Overview: ?? QP41M high temperature sewage ball valves are designed ball valve is the choice of all the new high-temperature sealing material for the valve seat by similar products made of PTFE sealing valve using life expectancy has increased 3-5 times. Functional secure, reliable sealing, friction force is small, easy to switch, high temperature, abrasion resistance, oil resistance, corrosion resistance, the use of long life and other advantages. Suitable medium: water, steam, oil and other acids, the use of temperature: ≤350 ℃. Second, product characteristics: 1, sewage valve seal seat, packing rings are made of high temperature, wear and corrosion resistance, resilience strong, self-lubricating, China's leading high-strength carbon graphite materials. 2, each valve have passed the strength test gas seal test, a series of open and close 50,000 times without leaks, was the most significant domestic energy action valve. 3, widely used in petroleum, chemical, rubber, paper, pharmaceutical and other professional, can replace the valve, piston valve, rapid discharge valve. Suitable medium: water, steam, oil and so on. 4, with features secure, reliable sealing, friction force is small, easy to switch, high temperature, abrasion resistance, oil resistance, corrosion resistance, the use of long life and other advantages.
