YFM lined ball valve advantages:
1. ISO 5211 universal mounting pad permits easy automation even with the valve in the pipeline.
2. Graphite bearing prevents side loading and extends seal life.
3. Cavity space minimizes the retention of process media.
4. Lining securely locked into the body by “T” slots and locking grooves;completely encapsulated ball and stem. Can handle
pressures from full vacuum to 275 psi (19 bar).
5. Extensive selection through 12 in (300 mm) for standard port and ball port valves.
6. Ductile iron body sections (ASTM A395 60-40-18) with high strength B7 fasteners are both rugged and rigid. B8 offered as alternate.
7. Designed in accordance with ASME B16.5 Class150 lb (DIN 2501⁄PN16) flange dimensions and ASME B16.10 face-to-face dimensions. Leak testing according to API 598 or DIN 3230 criteria.
An Atomac ball valve features:
Low, constant and predictable torque.
Thrust bearing supported stem to eliminate side-loading of packing and subsequent leakage during cycling.
Floating ball seat design for bubble-tight shutoff.
Long-life seats to minimize downtime and maintenance.
ISO 5211 mounting flanges.
All Atomac ball valves are fitted with a hand wrench as standard for manual operation. A gearbox option is also available
for valve sizes 6 in (150 mm) and above.
The modular construction of Atomac ball valves allows for easy use of all types of actuation devices. Actuators can be
mounted to the valves on-site, without removing them from the pipeline.
YFM pneumatic lined ball valve is a specialist in valve automation systems offering rack and pinion, heavy-duty and electric
actuators along with positioners, limit switches, engineered special control circuits and related accessories.
