Y-Pattern Bolted Bonnet
In addition to the line of globe valves bolted bonnet, FLUITEK ORSENIGO VALVES has added a line of same type of valve but with an inclined stem configuration, called Y-pattern type, as an alternative to the straight pattern, also called T-pattern. In principle, the Y-pattern configuration presents lower pressure drops at equal flow rate. The disc is normally either plug type or parabolic shaped. Cast body construction is normally used. Ends configuration is either with flanged ends or with butt weld ends.
Materials range from carbon steel to low alloy steel, to austenitic stainless steel, to nickel alloys. Materials are either to ASTM/ASME standards or to EN standards, either harmonized or calculated to design conditions. Pressure classes (per ANSI standard) are normally ranging from 150# to 300# to 600#. Size range depends on pressure class requirements, normally not exceeding 12”. FLUITEK ORSENIGO VALVES has anyhow no limits in relation to market requirements.
