Name: Festo 535904 Air solenoid valve MOFH-3-1/4-EX
Brand: Festo

Air solenoid valve MOFH-3-1/4-EX

The Festo 535904 is a 3/2-way monostable open industrial component featuring a 30.5 mm width, a 7 mm nominal width, and a plate seat structural design with a mechanical spring reset. It delivers a normal nominal flow rate of 800 l/min through G1/4 pneumatic working ports across an operating pressure range of 0.15 MPa to 0.8 MPa (1.5 bar to 8 bar). Electrical actuation operates via a solenoid coil ordered separately, supporting IP65 protection and c UL us recognition alongside ATEX, UKCA, and EPL Db/Gb explosion protection certifications for II 2G gas and II 2D dust categories within an ambient temperature range of -5°C to +40°C.

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.
