Name: Festo 535978 Air solenoid valve MFH-5/3E-D-1-S-C-EX
Brand: Festo

Air solenoid valve MFH-5/3E-D-1-S-C-EX

The Festo 535978 is a 42 mm wide electrical 5/3 exhausted piston gate valve featuring a mechanical spring reset and a normal nominal flow rate of 1200 l/min normalized to DIN 1343. Operating within a pressure range of -0.09 MPa to 1.6 MPa, this IP65-rated component utilizes a sub-base size 1 pneumatic working port according to ISO 5599-1 or G1/4, with operating voltage supplied via a separately ordered solenoid coil. Certified with CE and UKCA markings for ATEX category II 2G gas and II 2D dust environments, it supports explosive ambient temperatures from -5°C to +40°C with ignition protection types Ex h IIC T4 Gb and Ex h IIIC T105°C Db, alongside EPL Gb and EPL Db certifications.

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.
