[Ball valve] Features: (1) the fluid torque is small, and the full-diameter ball has basically no flow resistance. (2) Simple structure, small size and light weight. (3) Gap. 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 operation, fast opening and closing, from full open to full close only need to rotate 90°, remote control. (5) Easy maintenance, ball valve structure is simple, the sealing ring is generally yes, the replacement is 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 the overall sealing surface of the valve when it passes through. (7) Wide application, diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. (8) Because the ball valve is cleanable during opening and closing, it can be used in media with suspended solid particles.
Eccentric half ball valve Overview:
The eccentric half ball valve adopts the spring loaded movable seat structure, and the seat and the ball will not produce problems such as blocking or clearance, and the use of long. The V-shaped ball core has a shearing effect between the metal seat, which is suitable for media containing fibers, small solid particles and slurry. Control the pulp radius of the paper industry. 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 switched, the flow capacity is large, the pressure loss is small, the structure is compact, the universality is strong, the characteristic is estimated equal percentage, and the adjustment can be increased. Worm gear drive V ball valve also has the function of adjustment and positioning. V-type ball valve is suitable for Class150 ~ 600, PN1.6 ~ 10.0MPa, working temperature ≤200℃ on the pipeline, used to adjust the pressure and flow of throttling pipe medium, using different materials, can be applied to water, steam, oil, white, liquid, oxidizing medium, urea, salt water, neutral water and other media.
