Festo
543703
Air solenoid valve VMPA2-M1H-I-PI
The Festo 543703 is a 20 mm electrical industrial component featuring a 2x2/2 closed, monostable valve function and a piston gate valve structural design with a soft sealing principle. Operating on 24V DC within a pressure range of 3 bar to 10 bar (0.3 MPa to 1 MPa), this piloted unit delivers a normal nominal flow rate of 650 l/min to 850 l/min and utilizes a pneumatic spring reset method. It incorporates a positive overlap lap, non-reversible flow direction, signal status display, and detenting or non-detenting manual override, while offering IP65 protection and c UL us (OL) recognition for any mounting position.

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.
