Description
A nozzle (silent) check valve with flanged ends, suitable for pressure ratings PN10 to PN40. Available in sizes DN40 to DN500 with body materials including grey cast iron, ductile iron, and stainless steel options. Tested in accordance with EN 12266-A.
Selection notes
This check valve is a nozzle type and silent pattern, supplied for flanged installation.
Sizes run DN40 to DN500, in PN10, PN16, PN25, PN40.
The body is offered in GG25, GGG-40, GS-C 25 and SS 304, so the grade can be matched to the service rather than the other way round.
Seat and trim options are Brass, Bronze and SS. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
It is catalogued for Industrial Process.
Built to DIN EN 1092, BS 4504 and EN 12266-A.
