Name: Festo 535943 Air solenoid valve MFH-5/3E-1/4-B-EX
Brand: Festo

Air solenoid valve MFH-5/3E-1/4-B-EX

The Festo 535943 is a 32 mm wide electrical piston gate valve featuring a 5/3 exhausted function, mechanical spring reset, and G1/4 pneumatic working ports. Operating at 24V DC with an operating pressure range of 0.3 MPa to 1 MPa (3 bar to 10 bar), this component delivers a normal nominal flow rate of 1600 l/min through a 10 mm nominal width and adjustable exhaust air function. It carries CE and UKCA markings per explosion protection directives, featuring ATEX category II 2G for gas and II 2D for dust, along with EPL Db (GB) and EPL Gb (GB) certifications 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.
