Some of the most common types of valves are mentioned below along with their applications:

1. Rotary Valve: ( Types of Valves )

Rotary Valve : These valves are also referred to as quarter turn valves that mostly relies on the rotary motion of the flow obstructer. In maximum cases the rotation is limited to an angle of 90 degrees which makes it one quarter-turn, whereas, there are various other valves which can operate by the help of a larger degree of rotation that can have more than 2 positions in the regular operation.

Valves which are truly quarter-turn are found closing completely at an angle of 0˚ and completely opening at an angle of 90˚. Ball valves, plug valves, and butterfly valves are some examples of quarter- turn valves.

2. Linear Valve: ( Types of Valves )

There are 2 different types of linear valves first is multi-turn and the other is axial. These two valves are found relying on the linear motion of the flow obstructer, whereas they are quite different in terms of construction and operation.

3. Multi-Turn Rising Stem Valve: ( Types of Valves )

Multi-turn rising stem valves are those valves which move the obstructer by rotating a threaded rod also referred as stem which can be attached to the obstructer. These types of valve are mostly used for flow control applications.

4. Axial Valve: ( Types of Valves )

Axial valves are those types of valves which use pneumatic or electro-magnetic force in order to slide the obstructer along the axis. Coaxial valves angle seat valves are some of the examples of axial valves. These are the valves which are found acting fast and only used for an on/off process.

5. Actuated Valve: ( Types of Valves )

A actuated valve is referred to as a component of a piping system which is mostly used in controlling the flow of the media through the system. This control is developed by manipulation some different types of obstructer within the valve. Actuated valves are those which use mechanical devices known as actuators that operate the valve by the help of a power source like the compressed air or electricity.

Almost all the actuated valves are available in a manually operated version or in an actuated valve accompanied with a manual override. The most popular types of automated valves fall in one amongst these three main categories which are linear, rotary and self-actuated.

6. Ball Valve: ( Types of Valves )

These are referred to as those valves which are predominantly equipped with quick-acting 90-degree turning handles. These are the valves which use a ball in order to control the flow and to also provide an easy on-off control. It is usually accepted by most of the operators to be faster and easier in order to operate as compared to the gate valves.

7. Butterfly Valve: ( Types of Valves )

The butterfly valve is designed in a very compact way with a quick-acting rotary motion valve which is quite ideal for tight spaces. Butterfly valve bodies are found in various configurations.

8. Gate Valve: ( Types of Valves )

A gate valve is referred to as one of the most common type of valves which uses a linear motion in order to start or stop the flow. These valves are mostly not used in the flow regulation process rather are used in the completely open or closed positions.
