Festo
529991
Pressure regulator MS6-LR-1/2-D6-AS
The Festo part number 529991 is an industrial component featuring size 6 from the MS series, designed as a pressure regulator with an integrated pressure gauge and a product weight of 730 g. It provides constant output pressure with primary pressure compensation and secondary exhausting across an operating pressure range of 0.8 bar to 20 bar and a regulation range of 0.3 bar to 7 bar, delivering a normal nominal flow rate of 6500 l/min for compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases. The structural assembly incorporates any mounting position, a rotary knob with detent actuator lock that can be closed with accessories, and a maximum pressure hysteresis of 0.25 bar, alongside moderate corrosion resistance class 2 and VDMA24364-B1/B2-L LABS conformity for media and ambient temperatures ranging from -10 °C to 60 °C.
