Ball valves for water PERFECT

The VALTEC ball valves are dependable shutoff fittings. The structural specifics, the production technology and the used raw materials provide for long life of VALTEC ball valves, when used under Russian conditions. The diamond buffing of the shutoff ball and stem and their subsequent chrome or nickel-plating excludes the premature wear and tear of seat rings and spindle gasket, which are made of abrasive-effect resistant polymers. The ball valve is also resistant to the accumulation of foreign particles. The sealing of valve shutoff mechanism conforms to the highest class as per GOST y 9544-2005 – A. the bodies of the valves are made of brass brand CW617N (Euro standard EN 12165), the stem and shutoff ball gate are made of brass brand CW614N (EN 12164). The valve body has an extra galvanization coating. The areas of use of VALTEC ball vales includes: cold and hot water, including drinking water supplies, heating systems, transportation of compressed air, hydrocarbons and other liquids, which are noncorrosive to the valve’s material. The VALTEC PERFECT ball valves are: full bore, repairable and have extended life (average full life: 55 thousand cycles; average total operational life: 30 years). The PERFECT series valves are different in that they have reinforced more massive corpus with elongated connection thread. This provides for the extra durability of the fitting: the VALTEC PERFECT valves are recommended for use, in cases when there is a possibility of transfer of mechanical strains due to misalignment or temperature caused deformation of the connected pipes. The seat rings and stem gaskets are made of thermo-resistant Teflon, which permits the use of VALTEC PERFECT valves under working temperatures of up to +150°C. Nominal pressure: from 40 bar.
