Description
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 automate the process of controlling industrial valves, as well as to determine the position of the shut-off element of the valve.
The operating principle of the electric drive is to convert the electrical signal coming from the control device into rotational movement of the output shaft.
