â… ï¼ŽProduct Introduction
One-piece high-temperature ball valve The company designed the overall high-temperature ball valve is a new sealing material for the valve seat, by similar products PTFE do sealing ball valve, service life increased by 3-5 times. With stable performance, reliable sealing, small friction, switching light, high temperature, abrasion, oil, corrosion resistance, long service life and other advantages. High-temperature ball valves and globe valves, plunger valves, sewage valves, the structure of the length of the same, expanding the scope of use of ball valves, widely used in petroleum, chemical, rubber, papermaking, pharmaceutical and other industries, can be a substitute for the globe valves, plunger valves, fast sewage valves. Applicable media: water, steam, heat transfer oil and other acids, the use of temperature: ≤ 350 ℃.
Ⅱ．Product Features
(1) Fluid resistance is small, the full diameter of the ball valve is basically no flow resistance.
(2) Simple structure, small volume, light weight.
(3) Tight and reliable. It has two sealing surfaces, and the current sealing surface material of the ball valve is widely used in a variety of plastics, the sealing is good and can realize the seal. It has also been widely used in the vacuum system.
(4) easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90 °, easy to control from a distance.
(5) easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are relatively convenient.
(6) in fully open or fully closed, the ball and the sealing surface of the valve seat and the media isolation, the media through, will not cause the valve sealing surface erosion.
(7) Wide range of application, the diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied.
(8) Due to the ball valve in the opening and closing process of wiping, so can be used in the medium with suspended solid particles.
