Festo
535900
Air solenoid valve MFH-3-1/8-S-EX
The Festo 535900 is a 3/2-way closed, monostable industrial component featuring a plate seat structural design, a 26 mm width, a 5 mm nominal width, and a G1/8 pneumatic working port. Delivering a normal nominal flow rate of 500 l/min, this electrically actuated valve operates within a pressure range of -0.095 MPa to 1 MPa (-0.95 bar to 10 bar) using a mechanical spring reset method and an operating voltage applied via a separately ordered solenoid coil. Certified with IP65 protection and compliant with ATEX, UKCA, and EPL Db/Gb standards for explosive ambient temperatures between -5°C and +40°C, it supports gas category II 2G (Ex h IIC T4 Gb) and dust category II 2D (Ex h IIIC T130°C Db).

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.
