SLIMSEAL BUTTERFLY VALVE
	It is a wafer type Butterfly Valve with an integrally moulded elastomer body liner. Designed to outperform loose liners, SLIMSEAL's elastomer liner is moulded 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.
	SLIMSEAL 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 16. This permits its use in a wide range of applications making SLIMSEAL a truly versatile valve.
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.
SLIMSEAL's integrally moulded body liner is not subjected to streching, which is the cause for 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 SLIMSEAL's integrally moulded liner design.
In SLIMSEAL 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.
