Festo
531818
Pressure regulator MS6N-LRB-1/2-D5-AS
The Festo 531818 is an MS-series industrial component featuring a directly controlled diaphragm regulator of size 6 with a continuous compressed air supply and an operating pressure range of 0.8 bar to 20 bar. Designed with a rotary knob actuator lock with detent and a pressure gauge, this unit provides constant output pressure with primary pressure compensation and secondary exhausting across a 0.3 bar to 4 bar pressure regulation range and a normal nominal flow rate of 7300 l/min. It operates within a medium and ambient temperature range of -10 °C to 60 °C using compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases, maintaining a moderate corrosion resistance class of CRC 2 and a product weight of 747 g.
