Ball valves square measure movement motivated valves; they need found applications thanks to their easy style, low producing value and low maintenance necessities. this sort of valve is ideally suited to open/close sport and might be used for low to terribly high rate systems.
Ball valves square measure classed as quick acting as solely 1 / 4 flip (90 degree) of the valve disc is critical to fully open or shut the valve.
Ball valves square measure one in every of the foremost common valve varieties, the opposite varieties being the butterfly, gate, globe and plug valves.
This type of valve has the following advantages:
- can be quickly opened and closed with a quarter turn movement
- ensure a very tight seal without the need for high torque forces
- have a compact design (this is the main difference between a ball valve and a gate valve – which are both on/off devices)
The ball valve within the valve encompasses a hole through that the flow passes freely once it's totally aligned with the 2 ends of the valve. once the opening is totally perpendicular to the ends of the device, the valve is completely sealed.
Otherwise, once the opening is in the other position (perpendicular to the valve ends for instance) the flow is completely or partially interrupted.
