Festo
8223996
One-way flow control valve VFOE-LE-T-G18-Q8-F1A
The Festo 8223996 is an industrial component featuring an exhaust air flow control non-return function, a QS-8 pneumatic connection 1, and a G1/8 pneumatic connection 2. It is actuated manually via a rotary knob with latch, utilizes screw-in mounting, and operates within an ambient temperature range of -10 °C to 60 °C across an operating pressure range of 0.02 MPa to 1 MPa. This PBT-housed unit supports ATEX explosive prevention and protection for zones 1, 2, 21, and 22, and delivers a standard nominal flow rate of 170 l/min in the flow control direction.

Request a QuoteWhy 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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
