Description
Butterfly valves are designed for use as shut-off or regulating valves for flow control 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 performed 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 makes it possible to exclude the contact of the working medium with the materials of the main parts.
Electric quarter-turn actuators are designed for remote and local control of shut-off pipeline valves having a quarter-turn shut-off valve. They are used in various branches of national economy: in gas, oil, metallurgical, food industry, housing and communal services, etc.
A distinctive feature of this series of valves is that the flow path and disc are completely coated with PTFE, which prevents the working medium from coming into contact with the materials of the main components.
