electric and hydraulic inside screw knife gate valve

The product controls opening and closing of valve by the reciprocating pushing effect of electric-hydraulic linkage. It can bring about centralized or programmed control distantly for high-attitude dangerous area by mounting optional sensor or digital display. It is widely used in such sectors including metallurgy, electricity generation, coal mining, mining, water conservancy, etc., representing a kind of highly practical, upgraded substitute.

Features
