Festo
6420
Air solenoid valve MFH-5-1/2
The Festo part number 6420 is a monostable 5/2-way electrical industrial component featuring a 52 mm width, a plate seat structural design, and a normal nominal flow rate of 3700 l/min normalized to DIN 1343. Operating at a pressure range of 0.2 MPa to 0.8 MPa (2 bar to 8 bar), this piloted unit utilizes a soft sealing principle, mechanical spring reset, G1/2 pneumatic working ports, and an IP65 degree of protection with a detenting manual override.

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.
