Festo
546459
Basic valve LF-D-5M-MIDI-U
The Festo 546459 is a Midi size industrial component from the D series, featuring a sinter filter with a centrifugal separator and a metal bowl guard for vertical mounting within ±5°. It delivers a normal nominal flow rate of 251 cfm across an operating pressure range of 0 bar to 16 bar, utilizing a 5 µm filtration grade and a manual rotating condensate drain to achieve a 75 % condensate separation degree. Designed for compressed air and inert gases within a temperature range of 14 °F to 140 °F, the unit weighs 24.5 oz and maintains moderate corrosion stress resistance class CRC 2.

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.
