Key Features

→ Very low face to face dimensions hence space required for mounting is less than 10% of that of conventional valves. → Very low weight total weight is only approximately 1/6 the weight of a conventional check valve. → Short wafer body enables mounting the valve with shorter length fasteners of lesser number compared to flanged swing check valve Approximately 50% saving in cost of fasteners. → Considerable secondary advantages resulting in substantial savings in handling, packing, transportation, installation and maintenance. → Saving in terms of overall length required for piping. → Tightening torque to be applied on the companion flange bolting is lower due to face sealing O-rings. → Practically maintenance free due to fewer number of parts and simple construction. → Self centering in pipeline due to controlled outside diameter, enables easy installation.
