Festo
525206
Air solenoid valve MHE4-M1H-3/2O-1/4
The Festo part number 525206 is an electrical 3/2-way monostable open industrial component featuring a pressure relief poppet valve design with a nominal width of 4 mm and an 18 mm width dimension. This directly controlled valve operates at 24V DC with an operating pressure ranging from -0.09 MPa to 0.8 MPa (-0.9 bar to 8 bar, -13.05 psi to 116 psi) and delivers a normal nominal flow rate of 400 l/min through a G1/4 pneumatic working port. Built with soft sealing, an adjustable exhaust air function, a mechanical spring reset, and non-detenting manual override, the unit achieves an IP65 degree of protection and holds c UL us recognized (OL) certification for any mounting position.

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.
