Festo
8229689
Pressure regulator MS4-LR-1/8-D7-AD13-AS-WR
The Festo part number 8229689 is an industrial component featuring a directly controlled diaphragm regulator from the MS series in size 4, providing a normal nominal flow rate of 1000 l/min for compressed air as per ISO 8573-1:2010 [7:4:4] and inert gases. It operates within a pressure range of 0.8 bar to 14 bar, delivers a regulation range of 0.5 bar to 10 bar with secondary exhausting and a return flow characteristic, and incorporates a rotary knob with detent actuator lock that can be closed with accessories. Weighing 225 g with a CRC rating of 2 for moderate corrosion stress, the unit supports optional front panel or in-line installation in any mounting position while operating across a temperature range of -10 °C to 60 °C.
