DIAMOND
Diamond: larger sizes, smooth handling
The DIAMOND series by Enolgas Bonomi S.p.A. is the natural continuation of the JADE series for sizes from DN125 to DN200. The series features a ball retaining flange instead of a screwed sleeve like happens for the JADE series. The DIAMOND series is available starting from DN50 as an alternative to the JADE series.
The materials that may be required are: carbon steel (LF2), stainless steel (AISI316 and AISI304).
The DIAMOND series is characterised by the lateral seal in PTFE (on request in other special materials); upper seal in PTFE and O-ring; antistatic device; anti-burst pin; threaded holes; bar body.
The particular coupling between the PTFE gasket and the O-ring at the level of the valve pin, makes the same very soft in its opening and closing manoeuvre, as well as ensuring a high seal even in conditions more severe.
All valves are tested and verified before sale and are guaranteed for 2 years.
