Ball Valves: Resourceful Tips for Material and Design Considerations

This presentation is brought to you by Garamloha.com

Water is the vital fluid of nations and proper water regulation is indispensable. For controlling the stream, critical components are deployed through which every building, factories and industries keeps functioning in a seamless way. Amongst those components, Ball valves are extensively used in industrial and commercial piping systems for controlling the flow of liquids. These valves serve a great role in high pressure and high temperature conditions. There tight closing lid and shut off feature make them well suited for controlling the flow.

Proper shape of valve

A ball valve is a spherically shaped disc, with a hole centered through its middle part; and for monitoring the flow the hole should come in line with the two ends of the valves (it can be judged if lever and port lie on the same axis). Consequently, the flow is blocked as the port becomes 90 degree to the end of the valve. While designing the valves, special care is taken by the engineers for the valve’s components so that it regulates required flow, temperature and pressure conditions. And if designed accordingly these valves can easily sustain high temperature and pressures.


Different Ball Valves Designs:


1 Ball Design: A regular ball includes materials like copper, bronze, cast iron, brass and stainless steel. The port size and the position of the valve describe the design of the ball. The port size can be calculated by measuring the diameter of the port. Some common port sizes are Full port design, regular port design and reduced port design. Let’s have a look on them

2 Full port design: When the flow of fluids has to be resisted minimally full port designed valve is used. It incorporates a large ball that makes the port size similar as the pipeline’s inner bore.



3 Regular port design: Unlike, full port when the flow of fluids has to be resisted at maximum level then regular ports is used.

4 Reduced port design: This valve design fits well for end loaded valves that needs small diameter balls.

5 Floating Ball Design: A ball valve’s sphere is again classified in two ways, floating ball and Trunnion ball design. Floating ball is mainly used for low pressure and medium pressure applications.



7 Trunnion Ball Design: This ball support method is used mainly for extremely high pressure with ball valves having split body style.

6 Seat Design: Seat design is basically made from two types of materials: soft seats and metal seats. Soft seats are comprised of volatile materials such as PFA and TFE. And they are used for controlling leak-tight flow applications. Whilst, metal seats can sustain low temperatures and contact pressures. As they are coated with base metals like tungsten and satellite.

The type of valve needed by you largely depends on your specific requirements but if you have proper knowledge of what designs and materials are used for specific applications, then it would be much convenient for you to check for the right quality and durability of the valves. You may check Garamloha.com for such industrial products.
