Product description

Installation instruction:

Installation between ISO/DIN (all dimensions) and ANSI/BS flange adaptors (all except DN32 and DN125)
Installation with ANSI/BS flange adaptor: for wafer check valves DN40 to DN80 you have to use ANSI/BS flange adaptors with the next bigger dimension (example DN40 wafer check valve between DN50 ANSI/BS flange adaptor)
Centering by body diameter (ISO/DIN by D3, ANSI/BS by D)
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
The using of PVC-U pipe PN16 is only possible up to d63
Wafer check valves without reset spring are not recommended for pulsating flows (production of noise)
