Body Type

Ball Valves are usally designed in  1 piece for smaller sizes like 0.5 inches to 2 inches preferable. Above 2 inches ( including 2″) 2 piece and 3 piece design is used. 2 piece design consist of one side piece (sometimes called adaptor) and one body which houses the ball and seat ring. 3 piece design consists of 2 side pieces which houses the seat and seat ring and a body which houses the ball, stem and trunnion support. The body are usually bolted with the side piece along with a gasket or rings to prevent leakages.

Ball support

Depending on the size and pressure rating, ball in a ball valve is either of floating type or trunnion supported type. Usually in low pressure and small sizes, balls are floating type. Ball rests itself between the seats while connected with stem at the top of ball. In high pressure and large size valves the ball is usually heavy and hence a trunnion support is provided at the bottom of ball. The trunnion is like a small shaft at bottom and sometimes are assembled with trunnion guide plates.

Bore / Port

Depending on the process requirements, Ball Valves are usually availabe in full bore (port) or reduced bore. Full bore valve flow cross sectional area is same through out the equipment whereas reduce bore valves have a reduced cross sectional area in the ball and central area. Full bore valves are normally used in oil and gas and chemical applications where pigging required. These are covered in API 6D standard.

Seats

As per the application, ball valves seats are carefully selected either in completely soft seat, completely metal seat and fire safe seats which are soft seating surface as primary and metal sealing surface as a secondary. These seats are selected based on applications by process engineers and engineering consultants. Fire safe seating is normally covered under API 6D standard.

Industrial applications such as oil and gas, petrochemicals, chemical, power generation, mining and industries use this valves. What makes this useful is that its simple operation and its ability of flow control in addition to on-off duty. There is also a pre calculated pressure drop and flow CV calculation which is as per the flow requirements of process.
