PROGEF Standard
Wafer check valve type 369
Without spring

GF Piping Systems Gate Check Valves Type 369 is designed especially tough for large installations, demands low service effort and absolutely compact.

The Design is optimized for installations between ISO/DIN as well as ASTM connections.

The Gate Check Valve can be installed both in either horizontal or vertical direction.


Model:
  • Material: PP-H
  • Supporting eyelets for simple fitting
  • Suitable for vertical and horizontal mounting
Installation instruction:
  • Installation between ISO/DIN (all dimensions) and ANSI flange adaptors (all except DN32 and DN125)
  • Installation with ANSI flange adaptor: for wafer check valves DN40 to DN80 you have to use ANSI flange adaptors with the next bigger dimension (example DN40 wafer check  valve between DN50 ANSI flange adaptor)
  • Centering by body diameter (ISO/DIN by D3, ANSI by D)
  • It is necessary to use a special outlet flange adaptor PP or PE on the outgoing side of the wafer check valve
  • Sealing with special flange gasket (except DN32, o-ring)
  • A stabilizing zone of at least 5 times nominal diameter (DN) should be provided before and after the wafer check valve (10 times DN is recommended)
  • No direct installation on pump flange or following bend allowed
  • Wafer check valves without reset spring are not recommended for pulsating flows  (production of noise)
