[Ball valve] Features: (1) The fluid resistance is small, and the full-diameter ball valve has basically no flow resistance. (2) Simple structure, small size and light weight. (3) Tight. It has two sealing surfaces, and at present, the sealing surface material of the ball valve is plastic, which has good sealing property and can achieve sealing. It has also been used in vacuum systems. (4) Easy to operate, open and close fast, from full open to full close as long as the rotation of 90 degrees, easy to remote control. (5) Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. (6) When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when it passes through. (7) Wide application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. (8) Because the ball valve has wipeability in the opening and closing process, it can be used in the medium with suspended solid particles.
Pneumatic eccentric half ball valve Overview:
Pneumatic eccentric half ball valve adopts the spring loaded movable seat structure, the seat and the ball will not produce blockage or separation problems, and the use of long. There is a shearing effect between the ball core and the metal seat of the V-shaped incision, which is suitable for media containing fibers, small solid particles and slurry. Control the pulp of the paper industry appears. The opening and closing parts adopt V-shaped spherical structure, which solves the problem that the valve cavity is easy to deposit medium. When the valve is fully opened, the flow capacity is large and the pressure loss is small. Compact structure, strong versatility, flow characteristics of approximately equal percentage, adjustable large. Worm gear drive V-type ball valve also has the function of adjusting and positioning. The V-type ball valve is suitable for Class150 ~ 600, PN1.6 ~ 10.0MPa, and the working temperature is less than 200℃. It is used to adjust the pressure and flow of the medium of the pipe. The different materials are used for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, ammonia brine, and neutral water.
