Ball valves are low cost, compact, easy to set up and operate, and made from standard materials. They offer a fully developed flow with the slightest fluctuations and can be used for fluid balancing or adjustment. Generally, a quarter of a full turn can be fully opened and accordingly referred to as quarter-round ball valves. The low torque needed for this type of valve makes it an excellent candidate for fast manual or automatic operation. These valves have a long and reliable service
life. Their shape can be fully spherical or V-shaped.
The ball valve uses a spherical part as a flow controller. They are part of the design of the axis of rotation and include a flow passage.
