Stainless steel flanged ball valves

Stainless steel flanged ball valves
 

Product description:

Structural advantages and features:

Ball and plug valves belong to the same type of valve, small size and light weight valve structure simple energy-saving effect flow resistance medium flows through the valve, the equivalent flow over a period of straight pipes, the fluid resistance is minimized. Close and reliable valve sealing surface material widely used plastic, sealing, has also been widely used in the vacuum system of fluid into and out of the valve direction can be arbitrary choice, with two-way action; Easy to operate, opening and closing rapidly, from fully open to fully closed as long as rotate 90 °, to facilitate remote control and convenient operation, switch quickly, handle operation can be realized simply rotated 90 degrees switch pneumatic, electric can be any mobilization;. simple ball valve, seals are generally activities, the removal replacement more convenient. leakproof excellent results, with switch life can be 5-10 times higher than the other devices in the fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, does not cause the valve erosion of the sealing surface. Wide range of applications, from small to a few millimeters in diameter, large meters, from high vacuum to high pressure can be applied. Ball has been widely used in various sectors of petroleum, chemical, power generation, paper, atomic energy, aviation, rockets , as well as people's daily lives.
