For controlling the flow of pipeline, Usually globe valves are considered the industry standard. However, for large flow rate and need less reaction time working conditions
, ball valves also be considered.V type segmented ball valves and O-type ball valves are important ball valves types.These two types of ball valves have different structures and characteristics, suitable for different operating conditions.

Structure and Characteristics of two types ball valve

Ball valves design allows medium to flow straight through the valve, minimizing pressure drop across the valve, quickly-acting due to quarter-turn operation. The ball valves are available with a wide range of options for seats to fit specific customer applications such as metal seat, ceramic seat and soft metal seat.

Differences Between O type ball valve and Segmented ball valve

1.Different suitability for medium. O-type ball valves are mostly used for clean media or media with few suspended particles. V-type segmented ball valves often use ceramic seals or metal hard seals ,V-type segmented ball design also provides self-cleaning action and a strong cutting force ,which making it especially useful to be applied in media with viscous or abrasive media such as fibre, slurry and grime.The V-type opening port can cut through fiber medium, making v type ball valve widely applied in the pulp and paper industry, it effectively prevents medium blockage in the valve.

2.Different structure of two type of valve. The flow passage of an O-type
Ball valve is a complete circle with double-seat sealing. The V-type ball valve has a 1/4 semi-spherical valve disc with a V-shaped opening port on one side, using a single-seat seal.Designing with a full spherical valve ball for ceramic segment ball valve, with a V-shaped flow passage in double-seat sealing form.

3.Different suitability for process control requirements. O-type ball valves are mainly used for on-off control, with poor regulating performance. When equipped with an pneumatic actuator, they can achieve quickly on-off. With precise flow control performance, Segmented Ball Valve is designed with a V-type segmented ball which allows for equal flow percentage characteristics similar to globe valve. For precise small flow control, different segment ball designs of various Kv values are available. Segmented Ball Valves are not only used for flow control but also used for on-off control.

4. Different flow characteristics.O-type ball valves is quick opening about flow characteristic , suitable for on-off control. V-type Ball Valve has V-shaped ball. This allows the orifice to be opened and closed in a more controlled manner,The flow characteristic of V-type ball valves is approximately equal percentage,suitable for regulating control.
