Outline
ZDRO series of electric 0-off ball valve electric actuator and ball valve type 0 DN15 ~ 200 floating ball, DN250 ~ 300 is fixed ball structure.
The valve compact structure, small size, light weight, easy assembly and disassembly maintenance, flow through Young, small flow resistance, good sealing performance. The seat is flexible lip structure, with automatic wear compensation and relief role in the cavity, and therefore reliable sealing and long service life.
Widely used in petroleum, chemical, electric power, metallurgy, steel, paper, pharmaceutical, food, textile, light industry and other industries.
