Festo
531830
Pressure regulator MS6N-LRB-1/2-D5-A4-AS
The Festo 531830 is an industrial component featuring a size 6 MS series directly controlled diaphragm regulator with continuous compressed air supply, a rotary knob with detent actuator lock that can be closed with accessories, and an operating pressure range of 0.8 bar to 20 bar. This unit provides constant output pressure with primary pressure compensation and secondary exhausting, a pressure regulation range of 0.3 bar to 4 bar, a maximum pressure hysteresis of 0.25 bar, and a normal nominal flow rate of 7300 l/min for compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases. Weighing 747 g with a moderate corrosion resistance class of CRC 2 and VDMA24364-B1/B2-L LABS conformity, it operates in ambient and medium temperatures from -10 °C to 60 °C in any mounting position.
