方向控制阀用于改变、打开或阻止气动系统中介质的流动。压缩空气是气缸中常用的流体。这些阀的不同之处在于其操作元件的设计、开关位置数和流动路径以及驱动类型。有机械、气控或电控方向控制阀。
方向控制阀用于阻止、打开或改变介质的流动。例如，方向控制阀有一个供气口和几个排气口作为其工作输出。阀的名称（例如两位三通阀或三位五通阀）是基于端口数量和开关位置。
方向控制阀需要保证阀内的压缩空气或液压油被：

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.
Universal directional control valves
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.
A directional control valve is used to change, open or close the flow of a medium in a hydraulic or pneumatic system. Compressed air or a hydraulic fluid is the fluid that is normally used. The task of a directional control valve is thus to release, change or block cross-sections in the valve for the liquid or gas (fluid).
Directional control valves differ in terms of the number of ports and switching positions. A 3/2-way valve is used to switch a single-acting actuator, for example to switch a media flow and relieve the secondary side when the valve closes.
Festo 3/2-way valves are available in normally closed (NC) and normally open (NO) positions.
Festo offers a wide range of electrically and pneumatically actuated directional control valves for industrial automation. Our range includes standards-based valves as well as universal valves and application-specific directional control valves.
