Brand: Festo

One-way flow control valve VFOF-LE-BAH-G18-Q6

The Festo part number 8001459 is an industrial component featuring an exhaust air flow control non-return function with a piloted check valve and non-detenting manual exhaust function. It includes a QS-6 pneumatic connection 1, a G1/8 pneumatic connection 2, a QS-6 pilot air port 21, and an internal hex adjusting element for screw-in mounting in any position. The unit provides a standard nominal flow rate of 240 l/min in the flow control direction, a range of 120 l/min to 220 l/min in the non-return direction, and operates within a pressure range of 0.02 MPa to 1 MPa and an ambient temperature of -10 °C to 60 °C. Constructed with a PBT housing and ATEX certification for Zone 2 and Zone 22, it utilizes pneumatic actuation for the piloted non-return function and manual actuation.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
