546433

Basic valve LFR-D-MINI-A

The Festo 546433 is a mini D-series filter regulator featuring a structural design without a pressure gauge, set up for G1/8 pressure gauge connection, and equipped with a rotary knob with detent actuator lock. It delivers a normal nominal flow rate of 118 cfm under an operating pressure of 0.2 MPa to 1.2 MPa, maintaining a pressure regulation range of 0.5 bar to 12 bar with a maximum pressure hysteresis of 3 psi. The unit operates with compressed air as per ISO 8573-1:2010 [7:9:-] or inert gases, supports oil lubrication, and incorporates a 40 µm filtration grade with a fully automatic condensate drain and a metal bowl guard.

Why 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.
