Festo
546429
Basic valve LF-D-MINI-A-U
The Festo 546429 is a mini D-series industrial component featuring a sinter filter with a centrifugal separator and a fully automatic condensate drain housed in a metal bowl guard. Operating within a pressure range of 0.2 MPa to 1.2 MPa (2 bar to 12 bar, 29 psi to 174 psi) and a standard nominal flow rate of 157 cfm, this unit provides a 40 µm filtration grade with a 75 percent degree of condensate separation for compressed air and inert gas. It supports line installation or mounting with accessories at a vertical position within plus or minus 5 degrees, exhibiting a CRC 2 moderate corrosion stress rating and a product weight of 8.75 oz.

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.
