Product Name: Q941F electric valve Product Category: Q941F DN15 ~ 150 Product Information: Power: 24,220,380V, temperature: -20 ℃ ~ + 250 ℃, work pressure, said: PN16-63, nominal diameter: DN15-200mm, Material: WCB, 304,316,316L, Medium: steam, air, water, fluid, etc. Connection: flanged ball valve is an overview of electric rotary type valve angle of 90 °, the sealing performance, flow coefficient, flow resistance coefficient is small, simple structure, long life, easy maintenance. Equipped with air cylinder actuators, electric valve sub-switch type and adjustable models. Products are widely used in system control chemical, petroleum, textile, electricity, food and pharmaceutical, refrigeration, paper industry. Pipe flange connection can maintain good sealing performance, easy maintenance and replacement, easy closed pipeline. ■ fluid resistance, ball valves are the smallest of all kind of fluid resistance, even reduced diameter valve, the fluid resistance quite small. ■ stem thrust bearings reduce friction torque, can stem the long-term balance of operational flexibility. ■ good seat sealing performance, the use of PTFE seals and other material, the structure is easy to seal, and the ball valve sealing capabilities with the addition of media pressure increases. ■ stem seals and reliable, due to the rotary motion stem not only do the lifting movement, easy to damage the stem packing and sealing capability with additional pressure medium increases. ■ Because of Teflon and other materials have good self-lubricating, and friction losses small sphere, to help ball long service life. ■ download type stem and stem head convex order to prevent stem spray, such as stem seal damage caused by fire, convex order and the body can also be formed metal contact, ensure stem seal.
