Name: Festo 535921 Air solenoid valve MFH-5-1/8-L-B-EX
Brand: Festo

Air solenoid valve MFH-5-1/8-L-B-EX

The Festo 535921 is an electrical 5/2-way monostable industrial component featuring a piston gate valve structural design with a soft sealing principle and a 26 mm width. Operating at a pressure range of 3 bar to 10 bar (0.3 MPa to 1 MPa), this G1/8 pneumatic working port unit delivers a normal nominal flow rate of 1000 l/min utilizing a pneumatic spring reset method. Certified for hazardous locations with ATEX gas category II 2G, ATEX dust category II 2D, and IP65 protection, it complies with EU explosion protection directives, UKCA standards, and EPL Gb/Db requirements for explosive ambient temperatures between -5°C and +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.
