Festo
525186
Air solenoid valve MHE4-M1H-3/2G-1/4
This Festo 525186 industrial component is a 3/2-way closed, monostable pressure relief poppet valve featuring a direct electrical actuation type, a 4 mm nominal width, an 18 mm body width, and a G1/4 pneumatic working port. Operating at 24V DC within a pressure range of -0.09 MPa to 0.8 MPa (-0.9 bar to 8 bar, or -13.05 psi to 116 psi), the unit delivers a normal nominal flow rate of 400 l/min normalized to DIN 1343 alongside an IP65 degree of protection and c UL us - recognized (OL) certification. Additional features include a mechanical spring reset method, soft sealing principle, adjustable exhaust air function, non-detenting manual override, and 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.
