The V-type ball valve is a single-seat ball valve with a metal seat. The adjustment performance is the best in the ball valves, whose flow characteristics are equal percentages, and the adjustable ratio is up to 100:1. It has a shearing action between the V-shaped slit and the metal seat, and is especially suitable for media containing fibers, tiny solid particles, and slurry. During the...

Metal seated butterfly valve is that both sides of the seal are made of metal material or other hard materials. This seal has relatively poor sealing performance, but is resistant to high temperatures, abrasion and mechanical properties. Metal seated is often combined of such as: steel + steel, steel + copper, steel + graphite, steel + alloy steel. The steel here may also be cast iron, c...
