First, the side-mounted eccentric half ball Overview PQ347F / H side mounted eccentric half ball design similar to the three eccentric hard sealing butterfly valve, with easy operation, open process without friction, zero leakage, long life and other advantages. Half ball valve product supply network use is divided into: general-purpose valves, pipeline valves, slurry special valves, special gas valve, petrochemical special valves, special valves pulverized coal injection six series. Drive a manual, pneumatic, electric are three eight pressure levels (PN0.25 ~ 10.0Mpa) hundreds of specifications (40 ~ 1000) of half ball products. In the petroleum, chemical, metallurgy, electricity, gas and other industries are gate valve, globe valve, Y-valve, ball valve replacements. Is now selling in the steel industry, coal injection, aluminum industry, pulp, liquor and alumina powder conveying, hydraulic power industry (or dry) ash, petrochemical industry, gas industry and other occasions. Second, the side-mounted eccentric half ball industry Scope: Universal valves: rational design, compact structure, small flow resistance, good sealing, light and flexible, especially suitable for water, sewage, steam, pulp and other media of the low-pressure pipeline network, It can be formulated electric, pneumatic devices, enabling remote automation. (Water, steam, sewage, pulp, mud and other non-corrosive media)
