Festo
546514
Basic valve LFR-D-7-DI-MAXI
The Festo 546514 is a Maxi size Series D filter regulator featuring a structural design without a pressure gauge, set up for G1/4, and an actuator lock comprising a rotary knob with detent. It operates within a pressure range of 1 bar to 16 bar, a pressure regulation range of 0.5 bar to 7 bar, and provides a normal nominal flow rate of 1194 cfm using compressed air per ISO 8573-1:2010 [-:9:-] or inert gases. The unit includes a 40 µm grade of filtration, a manual rotating condensate drain with a 1.45 oz (US) max condensate volume, a metal bowl guard, and a maximum pressure hysteresis of 0.4 bar, while requiring 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.
