577534
Festo 577534 — Industrial Component
The Festo 577534 is a direct-controlled 5/2-way monostable industrial pneumatic valve featuring a 21 mm valve size, 5 mm nominal width, and a normal nominal flow rate of 500 l/min normalized to DIN 1343. This plate seat component utilizes a soft sealing principle with a negative overlap lap, internal pilot air supply port, non-reversible flow direction, and an adjustable exhaust air function alongside a mechanical spring reset method. Operating within a pressure and pilot pressure range of 0.25 MPa to 1 MPa (2.5 bar to 10 bar) and equipped with a 1/8 NPT pneumatic working port, the unit includes c UL us (OL) certification and supports any mounting position without manual override.

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.
