Industrial valves are mechanical devices that control the flow, pressure, and temperature of liquids, gases, or solids in systems and processes. They can open, close, or partially block passageways. Industrial valves are used in a wide range of industries, including chemical, petroleum, natural gas, electric power, metallurgy, pharmaceuticals, and food. 

Here are some characteristics of industrial valves: 

• Design

  Industrial valves come in many shapes and sizes, and can be simple or complex. 

• Components

  Most industrial valves have the same basic components: a body, bonnet, actuator, valve member, and seat. 

• Materials

  Industrial valves are made from a variety of materials, including aluminum, plastic, and stainless steel. 

• Actuators

  Actuators are used to actuate the valve. Common actuators include air cylinders, gears, electric motors, and solenoids. 

• Types

  Some common types of industrial valves include globe, butterfly, plug, and gate valves. 

Some examples of industrial valves include: 

• Globe valves

  These linear motion valves use a globe-shaped disc to regulate flow. Water faucets are an example of a globe valve. 

• Butterfly valves

  These valves have a disk that sits in the middle of a pipe and can swivel to admit or block fluid flow. 

• Plug valves

  These valves use a cone-shaped plug that moves aside when the handle is turned. 

• Gate valves

  These valves open and close pipes by lowering metal gates across them. They are often used for wastewater applications and neutral liquids. 

• Check valves

  These non-return valves prevent fluids from flowing backward. 

• Backflow preventers

  These are a module assembly of check valves that are used in high-hazard environments.
