Audco Slimseal Butterfly valve

Description

Audco Slimseal Butterfly valve:

AUDCO Butterfly Valves is a Wafer type Valve with an integrally-molded elastomer body liner. Designed to outperform loose
liners, AUDCO Butterfly Valves 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. A perfect FIT AND FORGET valve.
AUDCO Butterfly Valves 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 Valves a truly versatile valve.

LONGER LIFE VALVE

Integral molding permits maximizing the use of plasticiser 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.

EASY INSTALLATION

AUDCO Butterfly Valves 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.

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 get compressed around the shaft.

FOR CORROSIVE APPLICATIONS

AUDCO CHEMSEAL is a wafer type butterfly valve specifically designed for corrosive services. The body liner is formulated from Hypalon which is a synthetic elastomer having a chemical inertness very close to that of PTFE, but at the same time having the resilience of rubber. This design eliminates contact of the valve body and shaft from the line media. These valves find application on lines carrying aqueous acids, alkali solutions and majority of inorganic salts. The valve has a coating of epoxy paint capable of withstanding corrosive atmospheres
