If the ball is positioned in a way where the hole is not in this position, but rather in a perpendicular position to the passageway then the valve is closed as the fluid cannot pass through it. There are a number of different styles and options when decided what type of ball valve is right for you and your application, a skilled and experienced two way ball valve manufacturer will be able to diagnose your unique work environment to better equip you with a valve that will add value to your overall process.
Ball valves themselves are not all that reliable when it comes to applications where fine control of the valve is required such as in a throttle in a car. Two way ball valves are made with a single, straight passageway that is straight through the middle of the ball which makes two openings.
Three way ball valves are also available if your application so requires. Within the family of ball valves, there are three distinct types of ball valves a full port valve, a standard port valve and a reduced port valve. The standard port valve does have a regularly sized ball and the hole in the ball is smaller than the passageway, the full port valve has no flow restriction so when the valve is open there is no flow restriction.
Finally, the reduced port valve has a small ball with an even smaller hole, this creates significant flow restriction when the liquid passes through it.
No matter your application or unique needs, the right two way ball valve manufacturer will be able to suggest the best style and type of ball valve for your application. The best way to ensure that you get the right product which matches your vision is to work with the right manufacturer who has the skills, experience and knowledge to turn your vision into reality.
