BAXCELL NEEDLE VALVES
SPECIAL/OPTIONAL KEY FEATURES:
.BAXCELL offers Valves with Non-Rotating Tip Stem (NRT) thereby providing tight, repeatable shutoff without the galling or cross-scoring that occurs on V & ball-type stems. The NRT conical stem tip stops rotating when it contacts the seat so that any further torque turns the stem and not the tip. Furthermore, the conical stem tip seats in the same place every time – the more often the valve is seated, the better the mating with the seat is achieved. By contrast, the ‘V’ & ball-type tip does not seat in the same place every time, as the tip has no consistent axis of rotation. Consequently, every time the valve seats, a new seat mark is scored on the tip, creating multiple potential leak paths.
