525210

Name: Festo 525210 Air solenoid valve MHE4-M1H-3/2O-QS-8
Brand: Festo

Air solenoid valve MHE4-M1H-3/2O-QS-8

The Festo 525210 is a 3/2-way monostable open industrial component featuring a pressure relief poppet valve structural design with direct electrical actuation and a mechanical spring reset. Operating on 24V DC within a pressure range of -0.09 MPa to 0.8 MPa (-0.9 bar to 8 bar, -13.05 psi to 116 psi), this unit delivers a normal nominal flow rate of 400 l/min through a QS-8 pneumatic working port and a 4 mm nominal width. The IP65-rated assembly includes soft sealing, an adjustable exhaust air function, a non-detenting manual override, and c UL us recognition (OL).

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
