Because of the short delivery time needed, and more important because of the limited
face-to-face dimension required by the existing piping, normal cast steel valve bodies were precluded.
Face-to-face dimensions are in compliance with API 609 and MSS SP-68 standards.
It will enable us to offer customers complete peace of mind for highly specialised, bespoke orders while cutting lead times.C[yen] The bench can test valves with transition pipes with up to 4,700 mm
face-to-face dimensions as well as gate, globe and check valves up to 60 inches ANSI 600; 30 inches ANSI 1,500 and 24 inches ANSI 2,500, with a reaction force of 3000 tons.
The Spirax SafeBloc has ANSI or EN standard
face-to-face dimensions, enabling it to replace an installed standard single isolation valve, without pipework modifications.
The
face-to-face dimensions can be defined by the customer, making the STERI-TROL very easy to retrofit.
The exceptional sealing integrity, and minimum wear of an expanding gate is coupled with availability up to 48-inches 150 and 300 ANSI with short
face-to-face dimensions. Other new designs include the Danflo and Ball-Trol rotary control valves.
"The final design produced by NASA and Flowserve resulted in 40 to 60 percent shorter
face-to-face dimensions than conventional high-pressure valves."
Parts can be custom-built to compensate for offset flanges, special
face-to-face dimensions or unique configurations.
