Structural characteristics
Main Application
Used in the steam subcritical status for high-temperature/pressure sasturation, steam main pipeline and turbine
Electric on-off ball valve consist of angular travel electric actuator and ball
valve. Simple structure, rapid switching, large flow capacity, zero leakage,
applicable to the fluid with high viscosity, fiber-containing, solid particle. It
has been widely used in petrochemical, metallurgy, light industry and other
industrial automation field to cut-off or open the gas / liquid transport
pipeline.
