Festo: Redesigned actuator control valves
Festo’s VFOF, VBNF, and VBQF multi-functional pneumatic control valve series have been redesigned to create multi-functional units that are said to be less expensive to purchase than comparable solutions, more than 50% smaller in terms of height, save energy, and are easier and faster to install, troubleshoot, and maintain.
The new VFOF model LE-BAH features three functions in one unit and provides one-way speed control, manual override, and emergency stop functionality – holding a piston’s position even in the vertical position – in a single compact unit. The unit bolts directly to the actuator port and lies flat against the actuator for space savings in terms of height. The unit’s multiple ports are clearly labeled for fast, accurate installation, trouble shooting, and maintenance. Another model of the VFOF offers straightforward speed control in one direction in the compact form of the new series.
The new VBNF control valve delivers emergency stop and manual override in one unit. The new VBQF offers two options – manual override with a silencer and manual override without a silencer.
