PRODUCT INTRODUCTION
Single plate swing type wafer check valve comes with a short pattern sandwich type flangeless wafer body conforming to the API 6D and ASME B 16.10 face to face dimensions. The valve has a simple but reliable and robust construction.
The wafer check valve is ideal for pump discharge duties. The eccentric mounted hinge pin in combination with the disc seat guarantees a positive shut off of the returning media. Wafer Check Valves also available with Spring Loaded version on specific request.
The short face to face dimensions and low weight allows a simple space saving installation between the mating companion flanges. The wafer check valves are suitable for mounting between weld neck or slip on type companion flanges of different standards. The need for flange gaskets during installation is totally eliminated due to the in-built face sealing ‘O’ rings provided on the sealing face.

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.
