Festo
546426
Basic valve LFR-D-MIDI-A
The Festo 546426 is a Midi size D-series filter regulator featuring a structural design without a pressure gauge and a rotary knob with detent actuator lock. It operates within a pressure regulation range of 0.5 bar to 12 bar and an operating pressure of 0.2 MPa to 1.2 MPa, delivering a normal nominal flow rate of 487 cfm for compressed air as per ISO 8573-1:2010 [7:9:-] or inert gases. Equipped with a 40 µm grade of filtration, a fully automatic condensate drain with a maximum condensate volume of 1.45 US fl oz, and a metal bowl guard, this unit maintains a vertical ±5° mounting position.

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.
