Festo
535971
Air solenoid valve MFH-5/3G-D-3-C-EX
The Festo 535971 is a 5/3-way closed electrical industrial component utilizing a piston gate valve structural design with a mechanical spring reset method and a nominal width of 14.5 mm. It features a normal nominal flow rate of 4100 l/min, a 65 mm width, a 71 mm width dimension, an IP65 degree of protection, and pneumatic working ports configured for a sub-base of size 3 as per ISO 5599-1 or G1/2 connections. Operating at a pressure range of 0.3 MPa to 1 MPa (3 bar to 10 bar), the unit requires operating voltage via a separately ordered solenoid coil and carries CE and UKCA markings compliant with ATEX and UK EX directives for gas category II 2G (Ex h IIC T4 Gb) and dust category II 2D (Ex h IIIC T105°C Db) within an explosive ambient temperature range of -5°C to +40°C, alongside EPL Db and EPL Gb certifications outside the EU.

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.
