AIL Forged Steel Gate, Globe and Check Valves have established themselves the world over for their quality, reliability and long service. Rugged and compact in design, these valves are manufactured to the latest international designs using advanced manufacturing techniques and stringent quality control checks. The valves are regularly supplied to major Indian and international clients including oil refining companies and EPC contractors. They are available in a range of sizes starting from 1/4” to 2” (in reduced-bore design) and from 3/8” to 11/2” (in full-bore design).

AUDCO Butterfly Valve is a Wafer type Valve with an integrally moulded elastomer body liner. Designed to outperform loose liners, AUDCO Butterfly Valve elastomer liner is moulded directly in the body bore and vulcanised in-situ, making it last the entire life of the valve. The result – a valve that requires no form of maintenance. A perfect FIT AND FORGET valve. AUDCO Butterfly Valve is available in different combinations of body, liner and disc materials to suit a wide range of line fluids, a size range of 50 to 600 mm, and a pressure rating up to PN 20. This permits its use in a wide range of applications making AUDCO Butterfly Valve a truly versatile valve.

FLOATING BALL
AIL manufactures both floating and trunnion mounted ball valves. The standard AIL Ball Valve is of a floating-ball design, where sealing takes place by allowing the ball under pressure to move towards the downstream seat to effect a tight seal. The floating ball design is the universal choice for most process and utility applications.

THREE-PIECE DESIGN
Ball Valves featuring this design are the most easily on-line maintainable in their 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. This feature reduces maintenance downtime to a bare minimum.

TRUNNION-MOUNTED BALL
For higher sizes and pressure ratings, and for special services that require double-block and bleed features, trunnion-mounted ball valves are preferred by industry. In this design, sealing takes place by allowing the seat to move towards the ball along the flow axis. AIL manufactures a comprehensive range of trunnion-mounted ball valves, both in welded joint and in bolted body joint construction. These valves come with metal seats for cross-country pipeline applications and with soft seats for critical process applications.

SINGLE-PIECE / TWO-PIECE DESIGN
Single-piece ball valves are high performance valves, which come with a one piece integrally flanged body, in sizes of up to 200mm reduced bore and 40mm full bore. This design offers the unique advantage of eliminating the possibility of external leakage to the atmosphere through bolted body joints. These environment-friendly and high integrity valves are preferred in critical applications where the media is expensive, volatile or toxic, and where external leakage or wastage is unacceptable. The two-piece design complements the single-piece design in sizes of 250mm and above reduced bore, and 50mm and above full bore.

The Audco Taper Plug Valve,manufactured in sizes from ½” to 12”, is used on a wide variety of liquid,gaseous and slurry services. The tapered plug is held firmly into its taperedseat but can be so adjusted that complete leaktightness is achieved togetherwith smooth valve operation. The tapered seating surfaces of the plug and bodyare not exposed to the line fluid when the valve is in the open position, sothat the effects of corrosion and erosion are confined to the less importantparts of the valve. Also since there is a straight flowpath through the valve,there is very little resistance to flow and pressure loss is minimised.
