FLANGE FACING
Available all flange facings, according ASME/EN standards.TYPE C/D/E/F on EN flanges (A68) on casting and bar executions
TYPE RJ/LF/LG/SF/SG on ANSI flanges only on bar executions, due to the different face to face BW ASME B16.25 SW ASME B16.11
DOUBLE BLOCK & BLEED VALVES
Double ball + threaded/flanged drain valve that allow to drain the medium inside the body valve in closure (only on bar stock valves, special execution, customized face to face)
F1 FtF
Valve family ALFA 68 is available with special Face to Face according to standard DIN 3202-1 F1 (equivalent to EN558-1 Serie 1), specifically designed for chemical applications.Valve available both by forged bar and casting.
STANDARD EXECUTIONS
STEM O’RING
Maximum tightness from stem packing minimizing Fugitive Emissions (valve certified TA-LUFT e Fugitive Emissions EN 15848- 1/-2)
ANTISTATIC DEVICE ACCORDING API6D - ATEX 2014/34/UE
2 spring loaded balls guarantees electrical continuity between all metallic components of the valve
ANTI BLOW-OUT STEM DESIGN
In case of overpressure inside the valve it avoid the stem expulsion and the breakage of the operating element
