Festo
546456
Basic valve LFR-D-7-MINI
The Festo part number 546456 is a mini Series D filter regulator featuring a structural design without a pressure gauge, set up for G1⁄8, and incorporating a rotary knob with detent for the actuator lock. This component utilizes a 40 µm grade of filtration, a manual rotating condensate drain with a maximum condensate volume of 0.744 oz (US), and a metal bowl guard while operating within a pressure regulation range of 6.9 psi to 105 psi at an operating pressure of 1 bar to 16 bar. It achieves a normal nominal flow rate of 141 cfm using compressed air as per ISO 8573-1:2010 [-:9:-] or inert gases, maintaining a maximum pressure hysteresis of 3 psi and a vertical ±5° mounting position.
