Ball valves are used to control the hydraulic flow. These valves use a ball (a spherical obstruction) to start or stop the flow of fluid. Ball valves manufacturer places a ball to rotate at 90 degrees that opens and closes to perform the required function. Since it can be used for gas and liquid both, it is one of the most popular valves of the industries. Their lifelong service and reliable performance enhance the usages of ball valves. These are shutoff valves that rotate to a point where either part or entire hole gets covered. The ball allows the fluid to pass through the valve. When the hole gets perpendicular to the path, the flow of fluid gets stopped. The ball valves manufacturer has created a 90-degree turn to either fully open or fully close. This can also refer to as a typical ‘on-off’ control function.
The Operational Performance
Ball valves, somehow, belong to the same family of butterfly valves. When we will take a sneak peek into its manufacture, a ball valve has a perforated and pivoting ball. The size of the ball is equal to the pipe’s diameter.
The conventional valves often prove themselves worthless with their partial closing and opening positions. Their poor throttling ability, somehow, propels the users to use ball valves instead of conventional valves. These valves are considered less expensive as compared to many other valves.
The seat design of ball valves is considered as a specific performer. Ball valves usually include soft seats like PTFE, Buna-N, Neoprene, and Nylon, etc. These seat design materials limit the usage of valves and make them unsuitable for abrasive service.
Where the elastomeric seats fail to serve, metal to metal seats caters to the applications. They are able to handle high pressure and temperature. The fluid may include some solid particles. The valves which are having metal seating can incorporate things in a better way. The valves can be fitted with extension bonnets. Metal seated ball valves are used if a high level of safety is required.
Parts of a Ball Valve
The typical view of Ball valve includes the below parts –
The Patterns of Ball Valves
Based on the dimension and weight ball valves, these are classified into two patterns –
The piping design uses long pattern dimensions for the easy connections of pipe flanges. Apart from this, as short pattern ball valves are of lesser weight and dimension than the long pattern ball valves, they are used for other different purposes.
The Types of Ball Valves
The types of ball valves are classified on the basis of various factors. Different parameters have shown the different types mentioned below –

Further to this, other salient features are here –
Electrically Actuated Ball Valves
Electrically actuated ball valves can be classified into two forms, 2-way and 3-way ball valves. 2-way ball valves are a simple solution that rotates at quarter-turn from fully open to fully close. They typically operate slowly with an air-operated pneumatic actuator. On the other hand, 3-way electric ball valves offer the service for diverting applications like a bypass line.
Electrically actuated ball valves have their own different types where each has its own advantage and disadvantage. Some offer feedback via electrical signals and monitor the exact position. NEMA (National Electrical Manufacturers Association) rating describes the suitability of an electric actuator for a specific task.
Pneumatically Actuated Ball Valves
Pneumatically actuated ball valves are another kind of ball valves that are used for automation to control remotely. One uses pneumatically actuated ball valves on the demand for specific applications. These actuators use the pressure of compressed air to generate the required torque for turning a value.
The compressed air moves the piston linearly and further to this, the linear motion gets converted into the rotational. The pinion transfers the motion to the valve stem that further turns the ball either open or close.

Advantages of Ball Valve
Ball Valves are having multiple advantages for the industries –
Disadvantages of Ball Valves
As compared to advantages, the disadvantages of ball valves are negotiable while making the purchase –
