Product Details:

AUDCO Butterfly Valve is a Wafer type Valve with an integrally molded elastomer body liner. Designed to outperform loose liners, AUDCO Butterfly Valve elastomer liner is molded directly in the body bore and vulcanized in-situ, making it last the entire life of the valve. The result - a valve that requires no form of maintenance.

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.

Advantages of Integrally Moulded Liner

• Longer Valve Life- Integral molding permits maximizing the use of plasticizer in elastomer formulation. This ensures a smooth surface, thereby reducing friction between the disc and liner. In-situ vulcanization imparts greater strength to the liner. Reduced friction and high strength of the seat extend valve life.
• Superior Seating- AUDCO Butterfly Valve integrally molded body liner is not subjected to stretching, which is the cause of fatigue in loose-lined elastomers. Fatigue in elastomer results in excessive wear and subsequent tearing of the liner. A torn liner can be easily swept into the line causing extensive damage to expensive down-stream equipment. Though in valves with loose liners the seat can be replaced, by the time it is done the line fluid would have caused some corrosion to the valve body. This causes imperfect seating of the new liner, resulting in leakages. These drawbacks are eliminated in AUDCO Butterfly Valve integrally molded liner design.
• Easy Installation- AUDCO Butterfly Valve has a gasket integral to the body which eliminates the need for a separate gasket between the valve face and companion flange. In addition, as the liner is bonded to the body, it will not hang out or get pinched during installation. Damage to expensive replaceable seats is thereby eliminated.
• Shaft Sealing- In AUDCO Butterfly Valve the body liner incorporates flats at the top and the bottom where the shaft passes through, providing a wide sealing area. The secondary sealing is by two ‘O’ rings that are molded at the top and bottom of the seat, which gets compressed around the shaft. A weather seal at the top of the shaft prevents any ingress of foreign material into the valve.
• Fully Isolated Valve Internals- In the AUDCO Butterfly Valve, the rubber liner incorporates flats at the top and the bottom where the shaft passes through, providing a wide sealing area. This ensures the line fluid does not enter the stem area and get contaminated. The secondary sealing is by two ‘O’ rings that are molded at the top and bottom of the seat, which gets compressed around the shaft.
