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.
Explosion-proof quarter-turn electric actuators are designed for remote and local control of 90° rotation of a shut-off element of such types as a ball valve, etc. They are widely used in various sectors of the national economy: in the gas, oil, metallurgy, food industries, in housing and communal services, etc. They are suitable for use in industrial explosion-hazardous areas.
