Festo
577523
Air solenoid valve VUVS-LT20-T32H-MD-G18-F7-1C1
The Festo 577523 is a piloted 21 mm industrial component featuring a 2x3/2 open/closed monostable valve function, soft sealing principle, and negative overlap lap. It operates at 24V DC with an operating pressure range of 0.25 MPa to 1 MPa (2.5 bar to 10 bar), delivering a normal nominal flow rate of 600 l/min through G1/8 pneumatic working ports. Built with a plate seat structural design, mechanical spring reset, and adjustable exhaust air function, it includes both detenting and non-detenting manual override capabilities and achieves an IP65 degree of protection with a plug socket per IEC 60529. This c UL us recognized (OL) unit supports any mounting position, internal pilot air supply, and non-reversible flow direction with a 5.2 mm nominal width.

Request a QuoteWhy no listed price?
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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
