Festo
541655
Air solenoid valve MFH-5-1/8-120-EX
The Festo part number 541655 is an electrical 5/2-way closed monostable industrial component featuring a 70.5 mm width, a nominal width of 5 mm, and a normal nominal flow rate of 500 l/min through G1/8 pneumatic working ports. Operating on 120V AC within a pressure range of 0.18 MPa to 0.8 MPa (1.8 bar to 8 bar), this piloted valve utilizes a mechanical spring reset, soft sealing principle, negative overlap lap, and an adjustable exhaust air function. It achieves an IP65 degree of protection, features a detenting manual override, allows any mounting position, and carries FM 3026030 explosion protection certification spanning US Class I, II, and III (Divisions 1 and 2) alongside EPL Gb and Gc ratings.

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.
