Description
Butterfly valves are designed for use as shut-off or regulating valves to control flows in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Operating principle: The valves are opened and closed by turning the disk by 90°. Opening is made by turning the handle counterclockwise, closing - clockwise. The peculiarity of the gate valves of this series is the complete covering of the flow part and disk with PTFE material, which allows to exclude the contact of the working medium with the materials of the main parts.
