Festo
525199
Air solenoid valve MHP4-MS1H-3/2O-1/4
The Festo 525199 is an 18 mm wide electrical 3/2-way monostable open pressure relief poppet valve featuring a nominal width of 4 mm, a soft sealing principle, and an adjustable exhaust air function delivering a normal nominal flow rate of 400 l/min through G1/4 pneumatic working ports. Operating at 24V DC across a pressure range of -0.09 MPa to 0.8 MPa (-0.9 bar to 8 bar, -13.05 psi to 116 psi), this IP65-rated component utilizes a mechanical spring reset and non-detenting manual override for installation in any mounting position with a minimum grid dimension distance of 6 mm. It carries RCM compliance, c UL us recognition, and CE and UKCA markings in accordance with applicable EU and UK EMC and RoHS directives.

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.
