Festo
8193270
Check valve VBNF-CBA-Q6-Q6-F1A
The Festo 8193270 is an industrial component featuring a non-return valve function with pneumatic piloting and a non-detenting manual exhaust function. Constructed with a gray PBT housing, this part utilizes QS-6 pneumatic connections for connection 1, connection 2, and pilot air port 21. It operates with a normal nominal flow rate of 260 l/min, a standard flow rate of 500 l/min from port 1 to 2, and supports an operating pressure up to 1 MPa across an ambient temperature range of -10 °C to 60 °C using compressed air as per ISO 8573-1:2010 [7:4:4].

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.
