Eccentric half ball valve

Product Overview

Ball valves are widely used in oil, gas, coal and ore mining, refining and processing and pipeline transportation systems; in chemical products, medicine and food production systems; in hydropower, thermal power and nuclear power power power production systems; in urban and industrial enterprises water supply and drainage, heating and gas supply systems; in farmland drainage and irrigation systems; in metallurgical production systems An important mechanical product closely related to production and construction and people's life. The ball valve is sealed in all kinds of pipeline systems and is used to cut off or connect the medium flow, so that the medium can be transported to each designated point according to the predetermined procedure.

Structural characteristics

1. There is shear action between the cut ball core and the metal valve seat, which is especially suitable for medium containing fiber, small solid particles and slurry;
2. It has the ability of regulation and reliable positioning, the flow characteristic is approximate percentage, and the adjustable range is wide;
3. With the movable valve seat structure loaded by leaf spring, the valve seat and the ball core will not be jammed or separated. The sealing is reliable and the service life is long.
