Butterfly valves made of UPVC (unplasticized polyvinyl chloride) is designed to reliably shut off and regulate the flow of aggressive and neutral liquids at moderate pressures and temperatures. Due to its high chemical resistance and corrosion resistance, it is widely used in the chemical industry, water treatment systems and municipal infrastructure.
Quarter-turn electric actuators are designed for remote and local control of shut-off pipeline valves with a quarter-turn shut-off element. They are used in various sectors of the national economy: in the gas, oil, metallurgy, food industries, in housing and communal services, etc.
