Festo
8039821
Non return valve VMPA2-RV
The Festo 8039821 is an industrial component featuring an unlockable check valve function and pneumatic actuation with a nominal flow rate of 330 l/min. Housed in POM with a corrosion resistance class of 4 for particularly high corrosion stress, this part operates within a pressure range of 0.5 bar to 8 bar and ambient temperatures from -5 °C to 50 °C using compressed air per ISO 8573-1:2010 [7:4:4]. It supports any mounting position via a clip-type installation and permits operation with oil lubrication. Submit the exact part number, quantity, and application requirements to request a quote.

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.
