Pressure sealed stop valve DNOVA is designed for installation as a shut-off device on pipelines. Operating principle: When the flywheel rotates clockwise or counterclockwise, the rotational motion is transmitted to the spindle, and the spool attached to it closes or opens the passage hole in the housing. WARNING: The use of shut-off valves as control valves is prohibited.
