Festo
535937
Air solenoid valve MFH-5/3G-1/4-B-EX
The Festo 535937 is an electrically actuated 5/3-way closed industrial component featuring a piston gate valve structural design with a mechanical spring reset method. This 32 mm wide unit delivers a normal nominal flow rate of 1600 l/min through G1/4 pneumatic working ports, operating across a pressure range of 0.3 MPa to 1 MPa (3 bar to 10 bar) with an adjustable exhaust air function and IP65 degree of protection. Certified for hazardous locations, it carries a CE marking per the EU explosion protection directive, UKCA marking, ATEX category II 2G for gas and II 2D for dust, EPL Db (GB) and EPL Gb (GB) certifications, with ignition protection types Ex h IIC T4 Gb and Ex h IIIC T130°C Db for an explosive ambient temperature range of -5°C <= Ta <= +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.
