This series is suitable to the regulation which requests high precision, during the flux of control liquid.
Electric single-seated, double-seated and sleeve regulating valves are composed of common DKZ series or imported electric actuator series and valve body which valve core is single-seated type, double-seated type or sleeve type.
It has a lot of control way, flow characteristic equal percentage and linearity .
