Valve spheres are widely used in valve fittings, especially in petroleum, chemical, metallurgical and other sectors. Soft-sealed ball valves are used in flammable and explosive media equipment and piping systems, and fire and fire protection are also required. Ball valves are generally recommended for use in piping systems where double position adjustment, tight sealing performance, rapid opening and closing action, high pressure cutoff, low noise, cavitation and gasification, and low fluid resistance.
In addition, this accessory is also suitable for use in piping systems with lightweight construction and corrosive media. For example, when a regulating performance is required, a ball valve of a valve fitting having a special structure with a V-shaped opening is required. In petroleum, petrochemical, chemical, electric power, urban construction, metal-to-metal sealed ball valves are available for piping systems with operating temperatures above 200 °C.
From the application point of view, the valve fitting has a simple structural design, small volume, and low resistance to water flow, and is usually used for punching on the dry pipe, the branch pipe or the end thereof, and the flushing effect is good.http://www.dmgcastings.com/
