Festo
535901
Air solenoid valve MFH-3-1/4-S-EX
The Festo 535901 is a 3/2-way closed, monostable industrial component featuring a plate seat structural design with a 30.5 mm width, a 7 mm nominal width, and a G1/4 pneumatic working port. Operating at pressures ranging from -0.095 MPa to 1 MPa (-0.95 bar to 10 bar), it delivers a normal nominal flow rate of 800 l/min and utilizes electrical actuation via a separately ordered solenoid coil with a mechanical spring reset method. This IP65-rated unit carries CE and UKCA markings alongside ATEX and international explosion protection certifications for gas (II 2G, Ex h IIC T4 Gb, EPL Gb) and dust (II 2D, Ex h IIIC T130°C Db, EPL Db) within an explosive ambient temperature range of -5°C to +40°C.

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.
