The three types of control valves are:
Globe valves: These are the most common type of control valve and are used to regulate the flow of fluid or gas in a pipeline. They have a spherical body with a movable disk inside that can be positioned to adjust the flow rate. Globe valves are suitable for applications that require precise control and are commonly used in the chemical, pharmaceutical, and food industries.
Butterfly valves: These valves have a disc-shaped body that rotates around a central axis to regulate the flow of fluid or gas. They are typically used in applications where quick shutoff is required or where a large flow rate needs to be controlled. Butterfly valves are commonly used in the water treatment, HVAC, and power generation industries.
Ball valves: These valves have a spherical body with a hollow center that allows fluid or gas to flow through when the valve is open. A movable ball inside the valve body is used to regulate the flow rate. Ball valves are commonly used in applications where tight shutoff is required or where high pressure and temperature conditions are present. They are often used in the oil and gas, chemical, and petrochemical industries.
