Proportional directional valves are used in pneumatics and hydraulics to release or block the flow for compressed air or hydraulic fluid or to change the flow direction. They are usually indispensable final control elements in servo-pneumatic positioning systems.
The Festo proportional directional valve MPYE is a controlled piston spool valve that can be actuated in analogue mode. It has a position-controlled spool and can be combined with a position controller and a displacement encoder to create a precise pneumatic positioning system. Thanks to the throttle function for varying the cylinder speed and a 5/3-way function for varying the direction of movement, you can customise the MPYE to suit your needs. This proportional directional valve has flow rates of 100...2000 l/min.
比例方向控制阀 VPWP 也是受控活塞滑阀，但不是模拟受控，而是数字受控运行。VPWP 的特点在于集成有压力传感器，这些传感器具有监测功能，能够可靠地确保正确的力控制。此外，还有自动识别、诊断功能和集成的数字输出端（例如用于夹持或制动单元）等特点。在气伺服应用中，VPWP 几乎普遍与 CPX-CMAX 轴控制器和 CPX-CMPX 终端位置控制器搭配使用。
VPWS 比例方向控制阀是我们新开发的紧凑型产品，性能强劲。VPWS 是一种极其轻巧的 15 mm 插装阀，流量大。作为直接受控的中心阀，VPWS 可以安全而精确地控制气体流量，无论是氧气、二氧化碳、空气、氧化亚氮，还是惰性气体。不过请注意，VPWS 不带冗余和故障检测功能。VPWS 固定在连接板上。
