Description
A straight-pattern (SDNR) controlled check valve in cast steel construction, designed to PN 64 pressure rating. The valve complies with DIN 3356 design standard and features flanged end connections per EN 1092-2/B. Available in sizes DN15 to DN250 for globe valve applications.
Selection notes
This globe valve is a controlled check valve, straight type and sdnr pattern, supplied for flanged installation.
Sizes run DN15 to DN250, in PN64.
The body is GS-C 25 (GP240GH+N).
Seat and trim options are AISI 304. 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 3356, EN 558 Serie 2, DIN 3202 F2, EN 12266 and DIN EN 1092 PN 64.
