Festo 574245 VUVG-B14-M52-AZT-F-1R8L – 5/2 Solenoid Valve, 14 mm, External Pilot, 24 V DC
The Festo 574245 (type VUVG-B14-M52-AZT-F-1R8L) is a 5/2-way monostable solenoid valve from Festo’s VUVG series. It is designed for manifold (sub-base) mounting on a valve terminal or manifold rail. The valve is only 14 mm wide and uses a piston-spool design with air-spring reset and external pilot air supply. The external pilot lets it switch reliably even at very low working pressure or vacuum (−0.9 bar).
It delivers a nominal flow of 520–630 l/min at up to 10 bar. The 24 V DC coil uses only 1 W and is rated for 100% duty cycle. A covered, detenting manual override, IP65 protection and UL / CSA approval make it a compact, high-flow valve for automation, packaging, handling and assembly machines.
