Summary

We occupy the leading position in electrically operated valve industry

This series is suitable to the regulation which requests high precision during the flux of control liquidElectric single-seated, double-seatd and sleeve regulating valves are composed of ordinary DKZ series or imported electric actuator series and valve body which valve disc is single-seated type, double-seated type or sleeve typ.

It can achieve multiple accuracy control, flow characteristic equal percentage and linearity
