Festo VFOF Series Flow Controller, 10 Bar Maximum Operating Pressure, 60 °C Maximum Operating Temperature - VFOF-LE-BAH-G18-Q6, Numeric Part Number:8001459


This flow controller is a Compact pneumatic valve designed to control exhaust Airflow and adjust actuator speed in industrial systems. It provides one-way flow restriction for compressed Air and incorporates a piloted non-return with manual venting for temporary stops. The unit is suitable for indoor automation environments where a non-hazardous area device is required and supports push-in tubing at the inlet with a threaded outlet.

Features & Benefits


• Adjustable annular gap delivers precise piston speed control
• Operates across 0.2 to 10 bar to suit varied supply pressures
• Temperature range -10 to +60°C for standard industrial climates
• Push-in inlet enables quick connection to QS-6 tubing
• G1/8 threaded outlet offers secure downstream fitting
• Manual exhaust and pilot non-return provide temporary holding

Applications


• Suitable for controlling cylinder return speed in pneumatic actuators
• Ideal for use in machine control panels requiring temporary stops
• used with automated handling systems to fine-tune motion profiles
• Can be used for venting and holding functions during maintenance operations

What medium is the valve designed to handle?


It is intended for compressed Air complying with ISO 8573-1:2010 and may be used lubricated where required.

How is flow adjustment achieved?


Flow is altered by turning an internal-hex regulating screw that varies an annular gap within the housing.

What mounting and orientation options are available?


The valve is screw-in mounted and may be fitted in any orientation for flexible installation.

Which materials contact the medium and what are their characteristics?


The main housing is PBT, internal hollow bolt and sleeve are aluminium alloys, the regulating screw is brass, and Seals are NBR.

Is the unit suitable for outdoor corrosive environments?


It meets corrosion resistance class CRC2 for moderate indoor conditions where condensation may occur and is not specified for harsher external corrosion exposure.
