Key Features :

• Very low face to face dimensions hence space required for mounting is less than 10% of that 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.
