Festo
10873
Air solenoid valve MFH-3-1/4-S-NPT
The Festo part number 10873 is a 3/2-way closed, monostable industrial component featuring a piloted plate seat structural design with soft sealing principles and a nominal width of 7 mm. This electrical actuated valve operates within a pressure range of -0.095 MPa to 1 MPa (-0.95 bar to 10 bar) and delivers a normal nominal flow rate of 800 l/min through 1/4 NPT pneumatic working ports. It includes an adjustable exhaust air function, a mechanical spring reset method, a detenting manual override, and external pilot air supply ports, while achieving an IP65 degree of protection and c UL us recognition. Operating voltage is supplied via a solenoid coil ordered separately, and the component supports any mounting position with reversible flow direction.

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.
