Beschreibung
The wedge gate valve is designed for installation on a pipeline as a shut-off device in water supply systems and the chemical industry.
Operating principle: The wedge, connected to the spindle, is lowered or raised depending on the direction of rotation of the handwheel, closing or opening the flow section of the gate body.
The multi-turn electric drive is designed to control industrial shut-off pipeline valves, such as cast iron and steel gate valves, slide gate valves, ball valves, etc.
Application: the electric drive allows using the valves in automatic control systems for heat supply, water supply of civil and industrial facilities.
