A ball valve’s primary function is to stop the flow of liquid or gas utilising a revolving ball having an interior bore. Having a long lifespan ensures dependable sealing even when the valve is not used for an extended period.
On the other hand, these valves are more resistant to polluted media than most valves, and ball valves can also be utilised as control valves in particular configurations. This is a less widespread use since the flow rate can only be controlled to a minimal degree of accuracy compared to other control valves. On the other hand, the valve has certain advantages in this situation.
In a fluid system, valves perform five fundamental roles.
- Begins or ceases the flow of a system
- Control of flow: controls the flow of liquid or gas.
- Flow that is determined by the direction in which it is moving
- If a pressure spike develops, over-pressure protection securely releases system pressure.
- Excess flow prevention cuts off or controls the flow to avoid an uncontrolled process fluid leak.
Design of a ball valve
From chemical and petroleum production to papermaking and water treatment, a ball valve has been used extensively since its invention in the 1950s. A ball rests within a pipe, and that’s all this essential part has to offer. Liquids and gases can travel through when the hole at the centre of the ball is aligned with the pipe. The flow of substances stops when the ball spins and the hole is no longer in connection with the pipe.
A ball valve can tolerate high temperatures and pressures, especially the newer plastic models. They can also sustain and manage excessive volumes and pressures and high-velocity flows because of their durability.
A Ball valve provides several advantages:
A ball valve doesn’t require lubrication. It has a bubble-tight seal with minimal torque, ideal for low-torque applications.
It is common for them to be selected over more expensive options because of their low cost.
A long life expectancy: When used in the right conditions, these products will last for many years. It is less likely that a ball valve may be damaged or corrupted like other valves.
Installing a plastic ball valve is a snap since they are lightweight and easy to handle.
They may be utilised in a broad range of industrial applications to regulate the flow of liquids or gases.
Intense: Ball valves can sustain and manage high pressure, high volume, and a high-temperature flow. They are strong.
Simple to fix: When a valve has to be repaired, the seats are easily accessible.
Sizes of a ball valve
A ball valve comes in many sizes to meet the needs of a wide range of applications. Sometimes, they are colour-coded, so you know which one to utilise for your application. Typically, a ball valve’s diameter ranges from 0.5cm to 121cm.
Repairing and replacing a ball valve
The long service life of ball valves is one of the most commonly cited advantages. A plastic ball valve, which does not corrode like metal ones, is particularly well-known for its capacity to give many years of reliable service.
Of course, as with any part subjected to persistent stress, the damage might develop. Other advantages of certain ball valves are their ease of repair. Seals and seats are easily accessible for maintenance due to the simple construction of these components. Repairs may be done quickly and without requiring time or effort.
