Valves are mechanical devices that control the flow and pressure within a system or process. Industrial valves are built to control processes. Most utilities, from water to oil and gas, wouldn’t be able to function without heavy-duty, industrial-strength valves. So now that you know the importance of industrial valves, let’s get to know their different types, features, and usability.
Most common types of industrial valves fall into one of these following three main categories based on the mechanical motion of the valve:
- Linear Motion Valve: There are two distinct types of linear valves: rising stem (multi-turn) and axial.
- Multi-turn (rising stem) valves: Examples of multi-turn valves are gate valves, globe valves, pinch valves, diaphragm valves, and needle valves. These valve types are commonly used for flow control applications.
- Axial valves: Some examples of these are coaxial valves, and angle seat valves. These valves are typically fast-acting and only used for on/off process applications.
- Rotary Motion Valve: These types of valves rely on the rotary motion of the flow obstructer. In most cases, this rotation is limited to 90 degrees (one quarter-turn), however, some valves operate using a larger degree of rotation and have more than two positions that are used in regular operation. Valves that are quarter-turn are completely closed at 0˚ and completely open at 90˚. Examples of quarter-turn valves are ball valves, plug valves, and butterfly valves.
- Self-actuated valve: self-actuated valves use the system fluid to position the valve. Relief valves, safety valves, check valves, and steam traps are examples of self-actuated valves.
Despite high levels of variation, most industrial valves can be broken down into the same basic components which are as follows:
- Valve Trim
- Valve Member
- Stem Packing
