AUDCO LIMAL BUTTRLY VALV xperience In Motion LOWRV IDIA COTROL PVT LTD
AUDCO LIMAL is a Wafer type Butterfly Valve with an integrally moulded elastomer body liner. Designed to outperform loose liners, LIMAL s 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 IT AD ORT valve. AUDCO LIMAL is available in different combinations of body, liner and disc materials to suit a wide range of line fluids, a size range of 0 to 600 mm, and a pressure rating up to P 6. This permits its use in a wide range of applications making AUDCO LIMAL a truly versatile valve. ADVATA O ITRALLY MOULDD LIR LOR VALV LI Integral moulding permits maximising the use of plasticiser in elastomer formulation. This ensures a smooth surface, thereby reducing friction between the disc and liner. In-situ vulcanisation imparts greater strength to the liner. Reduced friction and high strength of the seat extend valve life. haft Weatherseal UPRIOR ATI LIMAL s integrally moulded body liner is not subjected to stretching, which is the cause for fatigue in loose-lined elastomers. atigue 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 LIMAL s integrally moulded liner design. rub crew AY ITALLATIO Integral O ring LIMAL 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. Integrally moulded liner Loose liner TM ALI In LIMAL Valves 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 moulded at the top and bottom of the seat, which get compressed around the shaft. A weatherseal at the top of the shaft prevents any ingress of foreign material into the valve. Integrally moulded liner Loose liner

AUDCO CHMAL Wafer Type Butterfly Valves or Corrosive Applications AUDCO CHMAL 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 PT, 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. LOR VALV LI Integral moulding permits maximising the use of plasticiser in elastomer formulation.

AUDCO CLAAL Wafer Type Butterfly Valves Hygienic Applications AUDCO CLAAL is a wafer type butterfly valve specifically designed for hygienic services. The body seat is formulated from food grade PDM or white itrile rubber, both synthetic elastomers which do not impart any toxic substance, colour, odour or flavour to the line media. This design eliminates contact of the valve body and shaft from the line media. These valves find application on Hygienic lines in food, dairy, beverages, pharmaceutical and other related industries. The valve has a white epoxy paint for providing corrosion resistance. These valves are available in a size range of 0 to 00mm and maximum pressure rating of 6 bar for PDM and bar for White itrile. L DRAII AD CAVITY R The CLAAL valve design incorporates a crevice free construction, which is a pre-requisite for valves to be used on hygienic services. A smoothly streamlined elastomer lining with a fully polished stainless steel disc ensures that there are no dead pockets or crevices in the valve. The body seat and disc of the CLAAL are contoured in such a way that it is impossible for any line media to remain stagnant inside the valve. The wiping action of the disc ensures that the seat is always maintained clean. UPRIOR ATI CLAAL s integrally moulded seats are not subjected to stretching unlike valves with a loose liner seat. This is because integral moulding literally makes the seat an integral part of the body. This design eliminates the possibility of the seat developing cracks or crevices. ULLY IOLATD VALV ITRAL In the CLAAL valves, 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 moulded at the top and bottom of the seat, which get compressed around the shaft. WATHRAL ATUR A weatherseal at the top of the shaft prevents any ingress of foreign material into the valve. This prevents absolutely any contamination of the line media by external means.
