阀和阀岛

在自动化技术领域，阀是用于控制气缸、无杆气缸、气动马达或气爪等执行器的气动元件。 就阀本身而言，通常将其分为气控阀、电控阀和手控阀。而 Festo 则开发有多种不同结构特点和多种派生型的阀产品。 此外，我们还可根据系统要求，提供与阀岛配合使用的阀。

用户再选择阀时，通常是为了完成最终装配或更换零部件。 最便捷的决策路径是，先确定正确的阀功能，再匹配合适的阀类型。

气动系统中的阀

在工业自动化领域，气动技术用于传递运动或力，通常借助压缩空气实现。 运动本身由驱动完成；在自动化技术中，驱动又由阀或阀岛进行控制。

简单气动系统的组成部分（示例）：

• 气缸
• 方向控制阀
• 附件

如果您正在排查速度、重复精度或循环时间方面的问题，除了驱动以外，通常还需要关注阀的流量控制与排气表现。

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 characterized 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.

Electrically and pneumatically actuated directional control valves from Festo:

• Standards-based directional control valves
• Universal directional control valves
• Application-specific directional control valves

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 sterilization, or for dosing and mixing, regardless of whether they are used for gases, highly viscous fluids, pastes or granulates.

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

Flow regulators: speed, stability and repeatability

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

Flow control valves from Festo:

• One-way check valves
• Throttle valves
• Pneumatic timers

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 familiarized yourself with the system. This service gives you a quicker and more cost-effective way to ensure your system is safe.
