Features

Applicable to constant flow water system in heating or refrigeration and balance the flow

Shut-off function integrated, can replace the globe valve

Stroke locking function integrated. The function can be opened after the system debugging. When the valve needs to beclosed for pipeline maintenance and overhaul, record the number of turns corresponding to the opening of the currentvalve before closing After maintenance, open the valve again to the recorded number of turs, thus secondary debuggingcan be avoided.

Equipped with measuring connect or to facilitate the quick connection with measuring equipment and save debugging time

Can be installed in the water supply or return pipeline
