ã€China Aluminum Network】 Aluminum profiles are mixed, and the amount of aluminum profiles purchased is too large to be checked one by one. To reduce unnecessary problems, it is very important to choose a good manufacturer if you understand the impact on the quality of aluminum profiles. For several major factors, you can buy reliable materials.
Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.

Alloy 6063 alloy is an alloy prepared with aluminum, magnesium and silicon as the main elements. Each element has a certain range of content, and the price of magnesium is high. In order to reduce costs, some manufacturers use less magnesium to allow less content. In some cases, the content of magnesium is lower than the allowable amount. Some factories add waste wires and waste pot aluminum waste pots to alloys, basically no 6063 alloy. As a result, the mechanical strength of aluminum profiles is very low, and can be as low as bending with two hands and one bend. It is commonly referred to as "noodle" as soft. This is one of the reasons why aluminum can be a few thousand dollars cheaper.
Regular aluminum manufacturers have internal standards when formulating alloy components, that is, within the range of various elemental contents, each factory has its own smaller range of variation, and the aluminum, magnesium and silicon ratios are very strict. Each plant has its own data and is confidential. Qualified formula-made alloys can guarantee the quality. Otherwise, the quality will not increase.
How to melt the aluminum alloy smelting furnace with a good 6063 alloy, what stove, which is also of great importance, and now the domestic use of the furnace has the level of the 40's, but also the level of the 90's, the poorer manufacturers use the original helium boiler. There are coal-fired, oil-burned, gas-fired and electrically heated smelting furnaces. Some stoves have chimneys, and some have no chimneys. The most commonly used are square-shaped furnaces (rectangular furnaces), advanced circular furnaces, and some circular furnaces can tilt aluminum water. On the tonnage of one ton, two tons, five tons, ten tons, twenty-five tons and fifty tons of aluminum melting furnace. More advanced, in the melting furnace below plus a static furnace, static furnace 6063 alloy used in the preparation of important, in addition to the slag in the furnace gas, standing, and then cast aluminum rod for extrusion use. The quality of the alloys formulated in the original coal-burning furnace and the modern circular furnace is not the same. In general furnaces, no matter what kind of fuel is burned, there should be a chimney, and most of the waste gas generated during the combustion of fuel can be discharged from the chimney. For example, no smoking exhaust waste residue is completely melted in aluminum water, so that aluminum bars for extrusion use are cast, and there are serious inclusion bubbles inside. This is one of the reasons for the inferior quality of aluminum profiles, which is also one of the reasons for the low price of aluminum.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
