OEMmanufacturing in Schroedahl &Arapp Spezial armaturen Co KG,A&T has, over a period of years,established a reputation formanufacturing high technologyvalves.
2 Their range of Triple anddouble offset Butterfly Valves aremanufactured in sizes from 80mmto 2500mm and pressures from10 Bar (class 125) to 260 Bar(class 2500).The A&T OEM range of Valves arein use at many of the WaterBoards, Water Authorities,Municipalities, Mines, Petrochemand Process plants, and Steelrefineries in Germany, as well and the Valves are available in wafer,lugged and double flangedconfigurations. A wide variety ofdrillings can be accommodated aswell as most European, Americanand Asian armaturen Triple OFF-SET DESIGN PRINCIPLE2A&T OEM Metal Seating High Pressure Butterfly Valves provide a bi-directional bubble tight shut off. This is achieved by introducingstate-of -the-art Triple Eccentric disc valve shaft is off-set against the seal, (1st off-set), and against the centre line of the valve (2nd off-set).
3 The seating edges aremachined with a continuously changing slope from an angleon top of the oval seat ring to an angleat the opposite side (3rdoff-set angular).This geometry ensures that the seat ring stays clear of the seat except at the final shut-off position, resulting in long seat life andoperating cycles in excess of 500 VALVE SEAL AND SEAT COMBINATIONA-T armaturen valve seal is manufactured from laminated stainless steel with PTFE or graphoil laminate depending on the applications. The sealis held in position by a bolt-on retaining ring and, together with the stainless seat ring, is easily gasket prevents leakage around the seal ring. The Metal seating valve can operate within a temperature of -249to + 600 C.
4 Valvedesigns for cryogenic applications are available on low temperature applications, the Metal seat can be substituted by a PTFE seat. A&T OEM High Pressure Butterfly Valves aremanufactured in a wide range of materials to suit most RINGSEALSEAT T~ RINGGASKETA&T OEM Metal seating Valves are certified fire safe in accordance with BS6755 : Part2:1987, and API 607, AP16FA.
