Festo VFOF Series Exhaust Air One-Way Flow Control Flow Controller, Push-In Inlet, G 1/8 Threaded Outlet VFOF-LE-BAH-G18-Q6

Festo VFOF-LE-BAH-G18-Q6 is an exhaust air one-way flow control flow controller engineered for demanding pneumatic applications. It brings reliable control to actuator return speed and integrates smoothly into environments requiring precise air management. Its push-in inlet allows quick and tool-free connection to QS-6 pneumatic tubing, while the G 1/8 threaded outlet offers robust adaptability to downstream fittings.

Operating between 0.2 and 10 bar, the unit is suitable for supply pressures in industrial systems and maintains optimal performance across temperatures from -10°C up to 60°C. The durable polybutylene terephthalate (PBT) housing resists moderate indoor corrosion, complemented by aluminium alloy internals, a brass regulating screw, and NBR seals for enhanced longevity and compliance with compressed air ISO standards.

Precise annular gap adjustment to fine-tune piston speed within pneumatic actuators. Manual venting and pilot non-return mechanisms provide temporary holding and maintenance flexibility. Flexible screw-in mounting orientation for ease in installation within control panels or automated assemblies.

Supports air quality requirements per ISO 8573-1:2010 (7:4:4); usable with lubricated air when specified. Meets corrosion resistance class CRC2 for moderate indoor exposure, not suitable for harsh outdoor environments. Suited for industrial machine automation, laboratory pneumatic control, maintenance safety, and HVAC motion tuning.

This flow controller is commonly employed to regulate actuator movement profiles, enable venting and safety holds during equipment maintenance, and ensure efficient handling of compressed air. Applications include machine control panels, automated material handling, pneumatic cylinder speed regulation, and controlled exhaust operations in laboratory or manufacturing settings.

Set up with screw-in mounting, the VFOF-LE-BAH-G18-Q6 operates reliably in any orientation, facilitating versatile placement in compressed air circuits. The internal hex regulating screw provides direct adjustment of air flow, allowing precise calibration for operational requirements.

For industrial users seeking robust air management, this Festo controller combines advanced design, compliance with RoHS and ISO standards, and proven reliability for routine and specialist pneumatic functions.
