Каковы 5 типов регулирующих клапанов?

Even for highly skilled professionals, selecting the appropriate control valve may be challenging. Gaining knowledge about regulating technologies and the many kinds of control valves and their applications is beneficial. Learn more about control valve types, technologies, and industry uses by continuing to read.

Ball Valves

Ball valves enable straight-through flow, which makes them very useful for separating flow. Depending on the type, they are simple to operate using air, electricity, or by hand. They also open and shut rapidly.

These valves rotate an internal hollow ball and have a robust three-piece body. This ball regulates the amount of fluid that may flow through.

Ball valves are ideal for managing large amounts of fluid at high pressure since they are strong and somewhat more expensive than other valves. The following uses for them are:

  • Managing structures
  • Water purification
  • Chemical synthesis

They work well for controlling steam and glycol mixtures, as well as hot and cold water. Ball valves keep fluid clean and protected from outside contamination by reducing the amount of openings where dirt may enter.

Butterfly Valves

Butterfly valves regulate flow in high-flow scenarios with a quarter-turn. They provide a fast and easy method to open or shut completely to minimize leakage and to start and stop the flow.

Like ball valves, these valves may be controlled manually, with electricity, or with air. But butterfly valves are less expensive and lighter.

Butterfly valves are adaptable, excellent for a wide range of industrial, water, and chemical applications, and come in a variety of materials and liner choices.

Businesses choose butterfly valves because of their superior flow isolation, rapid pressure recovery, and minimal pressure drop. Typical applications include:

  • Air conditioning
  • Control of exhaust gases
  • Services at high temperatures
  • Services using steam

Globe Control Valves

Globe control valves regulate flow in pipelines and other applications requiring significant pressure dips or high flow resistance.

The circular body of these valves has a two-part mechanism consisting of a fixed ring seat and a moving plug (disc). To control flow, a stem raises and lowers the stopper.

Globe valves are efficient and reliable, making them great for many uses, including:

  • Systems for chemical feeds
  • The primary steam vents and boiler
  • Methods for cooling water
  • Systems using fuel oil

Globe valves have a long service life, great performance, and optimized flow routes that reduce turbulence and pressure decreases despite their expensive cost.

Diaphragm Control Valves

Membrane valves, often referred to as diaphragm valves, typically consist of an elastomeric diaphragm and a plastic, wooden, or metal body having many openings. By shifting the diaphragm against a seat inside the body, the valve opens and shuts to regulate the flow.

The tight seal of these valves keeps liquids in your systems clean and sterile by preventing contamination.

Diaphragm valves come in a variety of designs and materials, making them adaptable to a wide range of applications. They can tolerate abrasive and corrosive substances and are appropriate for controlling clean water. For even more accurate control, they may be combined with process controllers or pneumatic control heads.

Self-Acting Control Valve

Utilizing a temperature-sensitive fluid that shrinks when cold and swells when heated, a self-acting valve regulates the flow of water. By use of an actuator, this movement opens and shuts the valve.

Common uses for these valves include the control of steam and water in heating and cooling systems. Common uses are as follows:

  • Air compressors
  • Air coolers
  • Industrial engines, boilers

Self-acting valves need no external power source to function, are very robust, and are simple to install.
