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.
