June 3, 2014
This new, innovative pneumatic control valve from Festo combines three control functions into a single compact unit.
The VFOF-LE-BAH valve simplifies assembly and commissioning and saves costs of ordering and logistics.
Combining functions provides:
  • High performance
  • Fewer components due to function integration
  • Faster assembly and commissioning
  • Freely selectable actuation direction
  • Space savings—up to 50%
  • Saving costs from ordering to logistics
  • Better energy efficiency from fewer interfaces
The VFOF-LE-BAH features a pneumatically controlled one-way flow control valve, non-return stop valves, and manual exhaust. Common applications for the valve are adjusting or stopping cylinder movement and de-energizing. The unit is 30 mm x 60 mm (1.18 in. x 2.36 in.) and weighs 30 grams (1.1 oz.). Function integration in the valve also creates a compact and attractive design that ensures quick, easy, and reliable installation.
