Festo
8821
Air solenoid valve JMFDH-5-1/8
The Festo 8821 is an electrical, piloted 5/2-way dominant bistable industrial component featuring a plate seat structural design and a 26 mm width. It operates within a pressure range of 0.25 MPa to 0.8 MPa (2.5 bar to 8 bar) with a normal nominal flow rate of 601 l/min, a G1/8 pneumatic working port, and an IP65 degree of protection. This c UL us recognized unit includes a soft sealing principle, an adjustable exhaust air function, a detenting manual override, and supports a maximum switching frequency of 16 Hz via a separately ordered solenoid coil.

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.
