Festo
540442
Air solenoid valve MHA1-M1LH-3/2O-0,6-PI
The Festo 540442 is a 10 mm wide industrial component featuring a directly controlled, monostable, open 3/2-way poppet valve with a mechanical spring reset and soft sealing principle. This electrical actuation valve operates at 24V DC with an operating pressure range of 0 MPa to 0.6 MPa (0 bar to 6 bar, 0 psi to 87 psi) and delivers a normal nominal flow rate of 10 l/min through a sub-base pneumatic working port. Designed with IP40 protection and c UL us (OL) certification under authority UL MH19482, the unit includes an adjustable exhaust air function, a 0.7 mm nominal width, and supports both detenting and non-detenting manual override in 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.
