Festo MFH-5-1/4 Solenoid Valve – 5/2-Way, Single Solenoid

Festo MFH-5-1/4 is a 5/2-way, single-solenoid pneumatic valve designed for industrial automation and compressed-air control systems. It features a nominal flow rate of 1,000 l/min, G1/4 pneumatic ports, and a mechanical spring reset. Its robust die-cast aluminium housing, NBR seals, and IP65 degree of protection support reliable operation in industrial environments. The solenoid coil must be ordered separately.
