Festo
151851
Air solenoid valve MFH-5/2-D-2-C
The Festo 151851 is a 5/2-way monostable industrial component featuring a piston gate valve design with a soft sealing principle and an 11.5 mm nominal width. This electrical actuated unit operates between 0.2 MPa and 1 MPa (2 bar to 10 bar) with a normal nominal flow rate of 2300 l/min, featuring a pneumatic spring reset, adjustable exhaust air function, and IP65 protection while conforming to ISO 5599-1 standards. Certified by UL and DNV, it utilizes a sub-base ISO 5599-1 size 2 or G3/8 pneumatic working port and requires a separately ordered solenoid coil for operation.

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.
