Description
Butterfly valves are designed to be used as shut-off or control valves for managing flows in heating systems, water supply systems, and technological processes in the food, chemical, oil and gas, pulp and paper, and other industries.
The reducer allows manual positioning of the shut-off element at a quarter turn, serving as an alternative to pneumatic, electric, or hydraulic quarter-turn actuators.
