Aluminum-plastic composite pipe ball valve (double cassette) is a combination of aluminum-plastic composite pipe and ball valve characteristics of the valve, it has some unique advantages and application scenarios. The following is a description of this valve in Chinese:

Aluminum-plastic composite pipe ball valve (double cassette) is usually used in the water supply pipeline system, it has good thermal insulation performance, the inner and outer walls are not easy to corrode, because the inner wall is smooth and the fluid resistance is small, making it very effective in fluid transportation. The connection mode of this valve is sleeve type, and the construction needs to pass strict pressure test to test the fastness of the connection, and to prevent frequent vibration leading to the loosening of the sleeve, the length direction should be sufficient installation amount to avoid pulling.

The material of aluminum-plastic composite pipe ball valve is usually composed of multi-layer structure, and there are three main types on the market: PE/AL/PE (polyethylene/aluminum/polyethylene), PE/AL/PEX (polyethylene/aluminum/crosslinked polyethylene), PEX/AL/PEX (crosslinked polyethylene/aluminum/crosslinked polyethylene). These materials make the aluminum-plastic composite pipe ball valve excellent in internal pressure strength, blocking oxygen and CO2, etc., suitable for avoiding the threat of corrosion of water pipeline equipment, and has good thermal conductivity and flame retardant effect.

The double-cassette ball valve itself has some unique characteristics, such as simple structure, easy to adjust, safe and reliable, good sealing, especially suitable for medium and small diameter pipeline under various pressure, temperature and media control through or cut off the pipeline medium opening and closing device. Its working principle is to press the ball on the outlet end of the valve seat by the medium pressure, the use of 90° transmission, to achieve rapid opening and closing, fluid resistance is small, fully open when the ball channel, the body channel and the cross-sectional area of the connecting pipe are equal, and are connected in a straight line, the fluid resistance of the ball valve is minimal in all kinds of valves.

The installation and use of aluminum-plastic composite pipe ball valve (double cassette) has a certain application basis at home and abroad. In China, aluminum-plastic composite pipe has developed rapidly, there are a variety of pipes to choose from, and with the progress of technology, its application prospects are broad. Although foreign applications are growing, the total amount and proportion are relatively small, especially in Europe, aluminum-plastic composite pipes are mainly used for building hot and cold water pipes and ground radiation heating.

In general, the aluminum plastic composite pipe ball valve (double cassette) because of its structure and material characteristics, has been widely used in the water supply pipeline system, and with the continuous development of technology, it has good prospects for development in the future market.
