Ball valves and globe valves are essential mechanisms in fluid control systems and they serve to open, regulate or block the passage of liquids and gasses. These valves can be found in a wide variety of industrial sectors, like the petrochemical, food and pharmaceutical industries, and they are also used in everyday items, such ashoses and plumbing appliances. Below we find out how ball valves are made, and the materials and machinery used to make them.
Ball valves and globe valves are shut-off mechanisms that use a perforated sphere which, as it turns, starts or stops the flow of a fluid. In order to open the valve, the stem joined to the sphere or ball must rotate. In this way, the bore with the valve inlet and outlet lines ups, permitting the passage of the fluid. This mechanism was created in the 20th Century. Historically, people have tried to seal elements in order to plug channels and pipes to control water. Due largely to its simple mechanism, durability and ease of use, the ball vale has been a popular choice in industry right from the start.
In terms of the materials used to make them, most ball valves are made from stainless steel, brass or carbon steel. These materials are the most commonly used because they are durable, resistant to corrosion and can be used in high pressure environments. However, the choice of materials largely depends on the intended use and the type of ball valve. There are different types on the market:
The manufacture of ball valves in the machine tool sector is a meticulous process which requires great precision because the mechanism is made up of different parts which must fit perfectly together. For example, CNC lathes are very suitable for manufacturing ball valves bodies, because they enable complex machining within very tight tolerances.
If we want to continue to enjoy such day-to-day things like watering our garden or enjoying a hot shower, we must ensure that whatever makes the water flow operates correctly. So, it's important to have a fleet of lathes that ensures quality in the manufacture of ball valves and there's no better choice than the TA series. The TA-15-YS-640 is ideal for manufacturing valve bodies because threads can be machined at both ends and holes made in radial planes.
