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.
Multi-turn electric drives are used to control various pipeline valves. The drives ensure reliable movement and retention of the shut-off element of the TPA in a given position, with a torque of 50 to 5000 Nm.
Multi-turn general-purpose industrial electric drives GZ are used in various sectors of public utilities, water supply, chemical, petrochemical industries, and the oil and gas complex.
