Audco Ball Valves

Full Bore Ball Valves

AB44 - Standard series

This 3-piece Ball Valve is the most easily on-line maintainable in its class. By removing three body connector bolts and loosening the fourth, the body can be swung away using the fourth bolt as the fulcrum, to carry out any installation or maintenance operation on the valve, thus reducing downtime. This valve can be offered in a wide variety of body and seat combinations.

AFB44 - Fire-safe series

This 3-piece fire-safe design Ball Valve features a secondary metal seat which renders the valve firesafe. When the seat is totally sublimated in a fire, the ball moves and rests against the lip, forming a metalto- metal seat, thus ensuring leak-tightness
