Wafer Check Valve

TEKO 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.

Considerable secondary advantages resulting in substantial savings in handling, packing, transportation, installation and maintenance.


Saving in terms of overall length required for piping.
