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:
作为气动领域创新的推动者,Festo 提供广泛的比例阀和方向控制阀。这将使您能够轻松可靠地执行最复杂的应用。立即了解我们的气控和电控阀产品组合,从适用于紧凑安装空间的超紧凑阀到适用于恶劣环境的超坚固阀。
电控或气控方向控制阀可用于控制驱动器。机械驱动阀可以使用 12、24、110 和 230 V 驱动。通用派生型包括两位三通或三位五通阀。例如,机械驱动方向控制阀通过按钮、扳手、踏板或弹簧进行切换。另一方面,气控阀由压缩空气驱动。
Festo 的标准方向控制阀可采用电动或气动驱动。
Festo 的电磁方向控制阀利用电磁的力来打开和关闭阀。在这种情况下,电磁被用作控制模块,用于“打开”或“关闭”线路中的介质 (NC/NO)。当对电磁施加电流时,阀被驱动,并根据控制类型,作为直接、伺服控制或强制先导操工作的阀运行。
Festo 核心产品范围推荐产品:
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.
