The ZSHVE/ZDRVE series cut-off ball valve is one kind of revolving cut-off ball valve, for air operated or electrically operated single unit construction measuring appliance's in execution unit, generally waits till the unit construction use with the solenoid valve. The seal form has the soft seal and seals two kinds hardly, in - 40~180 uses separately with - 60~450 the operating mode under. This serial products transmission efficiency is high, the thrust force is big, the sealing property is good, the rated flow coefficient is big, components interchangeability good and so on characteristics. This serial products is widely applied in Production department's and so on petroleum, chemical industry, drugs manufacture, metallurgy, light industry, papermaking, sewage treatment gas, the hydraulic transport pipeline intermediary archery target cut-off or opening, satisfied operating mode request.

   O the cut-off ball valve uses the cylinder plunger type pneumatic actuator or the DCL electric operator, O the cut-off ball valve's ball surface uses the special craft to carry on the carburizing, causes its surface smooth wear-resisting, the valve seat and the packing material use thermostablly, the wear resistant carbon fiber material to make, product mix exquisite reasonable, this series cut-off ball valve has the air operated plunger type O the cut-off ball valve and electrically operated O the cut-off ball valve two kinds; This serial products nominal pressure rank PN (mm) 1.6, 4.0, 6.4; Valve chest nominal size scope DN (mm) 15 ~ 300; The spillage standard has IV level, VI level; Valve core corner 90o, many kinds of variety specifications may supply the choice.
