Festo
525198
Air solenoid valve MHP4-M1H-3/2O-1/4
The Festo 525198 is an 18 mm wide electrical industrial component featuring a 3/2-way monostable open valve function with direct control and a pressure relief poppet valve structural design. It operates at 24V DC across an operating pressure range of -0.09 MPa to 0.8 MPa (-0.9 bar to 8 bar, -13.05 psi to 116 psi) with a normal nominal flow rate of 400 l/min and a G1/4 pneumatic working port. Constructed with soft sealing and an IP65 degree of protection, the unit includes mechanical spring reset, an adjustable exhaust air function, non-detenting manual override, and c UL us recognition.

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.
