Valves and valve terminals

Valves and valve terminals

Valves are pneumatic components that are used in automation technology to control actuators such as cylinders, rodless cylinders, motors or grippers. When it comes to the valves themselves, a distinction is made between pneumatically actuated valves, electric valves and manually actuated valves, which are available from Festo in many different designs and versions. In addition, we also offer valves for use with valve terminals, depending on the system requirements.

Valves in pneumatics

Pneumatics are used in industrial automation to transmit movement or force and this is usually done with the help of compressed air. The movement itself is carried out by actuators; these are in turn controlled by valves or valve terminals in automation technology.

Components of a simple pneumatic system (example):

  • Cylinder
  • Directional control valve
  • Accessories

Electric and pneumatic valves for every application area

Festo valves can be used across the board or configured individually, depending on the application. In addition to directional control valves, shut-off valves, flow or pressure regulators, our product portfolio also includes piezo valves – proportional pressure regulators that are characterised by their long service life and minimal energy requirements.

Electrically and pneumatically actuated directional control valves

A directional control valve is used to change, open or block the flow of compressed air in a pneumatic system.

Pneumatically and mechanically actuated process and media valves

Process and media valves from Festo control the different fluids in your machine during cooling, lubrication, cleaning, washing and sterilisation, or for dosing and mixing, regardless of whether they are used for gases, highly viscous fluids, pastes or granulates.

Process valves from Festo:

  • Hygienic butterfly valves
  • Angle seat valves
  • Proportional media valves
  • Ball valves

Flow regulators

Flow control valves – also called flow-through valves or throttle valves – are used in pneumatics to regulate the flow of compressed air.

Functional safety: valves and valve terminals from Festo

The functional safety of an application is crucial, especially in pneumatics, since – unlike in electric systems – the work here is usually done with common hardware components. In addition to comprehensive product information on our website, our project engineers are available to provide you with expert advice until you have familiarised yourself with the system. This service gives you a quicker and more cost-effective way to ensure your system is safe.

FAQs – frequently asked questions clearly answered

What is a pneumatic valve?

Like any valve, pneumatic valves have a control function to determine the amount of gas or compressed air that is allowed to flow through. With a pneumatic valve, the flow is controlled by a pneumatic signal.

What is the difference between electric and pneumatic valves?

Electric pilot-actuated valves or pneumatic valves can be used to control actuators. Electric pilot-actuated valves can be operated with 12 V, 24 V or 230 V. Common variants are, for example, 3/2- or 5/2-way valves.

Pneumatic valves, on the other hand, are actuated by compressed air.

Which valves does Festo offer?

The product range of valves and valve terminals from Festo includes:

  • Directional control valves
  • Shut-off valves
  • Flow regulators
  • Proportional valves
  • Process and media valves
  • Electrical peripherals

Pneumatic valves

A pneumatic valve is a component with which air flows can be switched. It can be actuated in different ways. Pneumatic valve classification: air, mechanical, manual and electric. Thanks to the easy connection to a control level, for instance a PLC, the electric pneumatic is the most appropriate. This not only has switching functions, but also for example a one-way flow control valve. This allows the speed of the air flow to be controlled. Compare this for example with a speed regulator electro motor. From a safety point of view, it is important that valves are intrinsically safe for certain applications. Think of ATEX environments, for instance. Pneumatic valves are often compared with an electric hydraulic valve. Festo is one of the most important valve manufacturers/ suppliers in Europe. Contact our sales team in IE and they will give you an overview of the full range of quality valve technology that we have. They also inform our customers about installation, operation, and delivery time.

Types of valves

Within pneumatics, a wide choice of different valves is available. Solenoid valves , for example, can not only switch the air but also individually regulate the pressure in the same ducts. Solenoid valves are not only operating pneumatic, there is also proportional hydraulic technology. In addition to the proportional valve, our company also offers switching valves, electrically actuated valves, manual valve, normally open valve and spring offset pneumatic valves that refers to the manner in which air flow paths is switched.

Air valves

There are many different types of variants, from shut-off to flow control valves. While the shut-off variant determines the flow rate, the pressure air does the same for the air pressure. For customer applications actuated using the medium of oil, the pressure air valve is also called hydraulic. For electrical actuation, the most common solenoid valve 12v is used. Other customer applications within compressed air are versions with manual actuation, these are operated using a push button, lever or other means of actuation.

Valve islands

The valve island concept is often used for larger requirements, because of its compact and bundled solution. In pneumatics this is called a valve island or valve terminal. It is very efficient for company names of machines and to reduce the consumption of the air supply. In addition, the valve islands from Festo have different levels, from a multiple valve block (individually wired) to integrated PLCs. For switches that are controlled using hydraulic oil, the electric hydraulic valve block technology is used, which can be found in our educational courses for expertise.
