A directional control valve is used to change, open or block the flow of a medium in a pneumatic system. Compressed air is the fluid that is normally used in pneumatic actuators. The valves differ in terms of the design of their control element, the number of switching positions and flow paths as well as the type of actuation. There are mechanically, pneumatically or electrically operated directional control valves.
Directional control valves are used to block, open or change the flow of a medium. Directional control valves have, for example, a supply port and several exhaust ports as their working outputs. The designation of the valves, for example 3/2- or 5/3-way valve, is based on the number of ports and switching positions.
Directional control valves need to ensure that the compressed air or hydraulic fluid in the valve is:
As an driver of innovation in pneumatics, Festo offers a wide range of proportional valves and directional control valves. This will allow you to implement even the most complex of applications reliably and easily. Discover our portfolio of pneumatically and electrically actuated valves now, from extremely compact valves for tight installation spaces to extremely sturdy ones for harsh environments.
Electric or pneumatic directional control valves can be used to control actuators. Mechanically actuated valves can be actuated using 12, 24, 110 and 230 V. Common variants are, for example, 3/2- or 5/3-way valves. Mechanically operated directional control valves are switched by a button, a lever, a pedal or a spring, for example. Pneumatic valves, on the other hand, are actuated by compressed air.
Standards-based directional control valves from Festo are available with electric or pneumatic actuation.
Solenoid-operated directional control valves from Festo use the force of electromagnets to open and close valves. In this case, the solenoid is used as a control module that "opens" or "closes" the medium within a line (NC/NO). When an electrical current is applied to the solenoid, the valve is actuated and, depending on the control type, operates as either a directly, a servo-controlled or force pilot operated valve.

Proposed products from the Festo Core Range:
The Festo product range of application-specific directional control valves extends from compact solenoid valves to pilot valves, which are used when valve terminals are not technically or economically feasible.
方向控制阀用于改变、打开或关闭液压或气动系统中介质的流动。常用的流体是压缩空气或液压油。因此，方向控制阀的任务是释放、改变或阻止阀中用于液体或气体（流体）的横断面。
方向控制阀在端口数量和开关位置方面有所不同。两位三通阀用于切换单作用驱动器，例如切换介质流并在阀门关闭时释放出口。
Festo 两位三通阀可在常闭 (NC) 或常开 (NO) 位置使用。
Festo 提供各种用于工业自动化的电控和气控方向控制阀。我们的产品范围包括标准阀以及通用阀和特定于应用的方向控制阀。
