Name: Festo 535974 Air solenoid valve MFH-5/3G-D-3-S-C-EX
Brand: Festo

Air solenoid valve MFH-5/3G-D-3-S-C-EX

The Festo 535974 is an electrical 5/3-way closed industrial component featuring a piston gate valve structural design with a mechanical spring reset. Measuring 65 mm in width with a nominal width of 14.5 mm, this unit delivers a normal nominal flow rate of 4100 l/min through an ISO 5599-1 size 3 sub-base or G1/2 pneumatic working port across an operating pressure range of -0.09 MPa to 1.6 MPa. Rated with IP65 protection and certified with CE and UKCA markings for ATEX category II 2G gas and II 2D dust explosive environments, the assembly operates via a separately ordered solenoid coil within ambient temperatures from -5°C to +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.
