Festo 8031545 VUVG-B18-B52-ZT-F-1R8L – 5/2 Bistable Solenoid Valve, 18 mm, 24 V DC
The Festo 8031545 (type VUVG-B18-B52-ZT-F-1R8L) is a 5/2-way bistable (double-solenoid) valve from Festo’s VUVG series, made for manifold (sub-base) mounting. It is 18 mm wide and uses a piston-spool design with external pilot air supply, so it switches reliably even at low pressure or vacuum (−0.9 bar). Being bistable, it holds its last switching position when the signal is removed. That makes it a good choice where a cylinder must stay in place after a power or signal loss.
With a nominal flow of up to 1000 l/min at up to 10 bar, this is the high-flow size of the VUVG range. Each 24 V DC coil uses only 1 W and is rated for 100% duty cycle. The valve also has a covered, detenting manual override, IP65 protection and UL approval. It is a strong choice for larger cylinders and high-flow applications in automation, packaging and handling machines.
