Product Description
The Festo VFOE is a manually adjustable one-way flow control valve that is barely thicker than a tube and just as lightweight, allowing direct mounting on pneumatic drives for space-constrained applications such as electronics assembly . This low-cost solution for standard applications enables simple and reliable adjustment of pneumatic cylinder speed with a push-to-lock function, making it ideal for fast commissioning and sustainable operation through the use of alternative materials .
Key Features & Advantages:
Barely Thicker Than a Tube & Lightweight: Extremely compact dimensions with a PBT housing weighing as little as 9.5 g , allowing direct mounting on cylinders even in the tightest spaces such as electronics industry applications .
Simple and Reliable Adjustment with Push-to-Lock: Rotary knob with detent or slotted head screw adjustment options ; colour-coded actuator button (blue for supply air/exhaust identification) makes selection quick and error-proof .
Direct Cylinder Mounting & 360° Rotatable Outlet: The valve can be mounted directly on the drive, barely thicker than a tube; the tube outlet direction is adjusted by simply turning the top of the outlet, eliminating the need for additional fittings .
Supply Air and Exhaust Air Variants: Available in both supply air (VFOE-LS) and exhaust air (VFOE-LE) flow control functions, enabling independent adjustment of cylinder advance and retract speeds .
ATEX Hazardous Location Certified: Suitable for use in Zone 1, 2, 21, and 22 explosive atmospheres , with cleanroom compatibility up to Class 4 according to ISO 14644-1 .
