The DNOVA wedge gate valve is designed for installation on pipelines as a shut-off device in water supply systems and chemical industry.
Electric multi-turn actuator DNOVA is designed to automate the process of controlling industrial valves, as well as to determine the position of the valve shut-off device.
The DNOVA wedge gate valve is designed for installation on the pipeline as a shut-off device in water supply systems and chemical industry.
Reducer DNOVA is designed to increase torque for manual operation of shut-off and control valves with non-retractable spindle, as well as to create a force to ensure the required tightness in the gate valve.
