Forged Brass Solenoid Valve, 03F Series + Connector + Coil | AIGNEP

The AIGNEP Series 03F guided diaphragm solenoid valve is a forged brass solenoid valve that combines the operating principles of direct-acting and servo-assisted valves, achieving superior performance and a lifespan up to five times longer than traditional valves. Designed for extreme conditions, it operates from 0 bar differential pressure and withstands up to 25 bar. Available in 1/4" and 1" BSPP connections, with interchangeable coils in 24 VDC, 110 VAC, and 220 VAC. ATEX II 2G/D and CSA C22.2 certified for potentially explosive environments. Manufactured in Italy by AIGNEP, a European benchmark in pneumatic and hydraulic components.
