Brand: Festo

One-way flow control valve VFOE-LE-T-G14-Q8-F1A

Engineered by Festo, part number 8223998 is an industrial component featuring an exhaust air flow control non-return function with a QS-8 pneumatic connection 1 and a G1/4 pneumatic connection 2. This device utilizes a manual actuation type with a rotary knob featuring a latch, screw-in mounting, and a durable PBT housing material rated for an ambient temperature range of -10 °C to 60 °C. It delivers a standard nominal flow rate of 500 l/min in the flow control direction and operates across a pressure range of 0.02 MPa to 1 MPa (0.2 bar to 10 bar / 2.9 psi to 145 psi) using compressed air as per ISO 8573-1:2010 [7:4:4].
