Cryogenic globe valve
Item：Parameter
DN：≤16“(DN400)
PN：≤900LB(PN15MPa)
Connection：RF/SW/BW
Standard：API 623/BS1873/BS6364
Temperature：-196℃~+85℃
Media：LNG、O2、N2、Ar etc. liquid or gas
Material：CF3M/CF3/CF8M/CF8(F316L/F304L/F316/F304)
PCTFE bushing is added to the middle of the valve stem to prevent the valve stem from instability
The sealing surface is welded with hard alloy to increase the service life (Figure 2) ；
The upper sealing seat is raised to ensure the safety of the middle cavity (Figure 1);
The stuffing box is elevated to effectively protect the stuffing;
The drip plate effectively prevents the condensed water from flowing into the insulation layer;
100% radiographic inspection of all pressure-bearing welds.
