Festo
8086639
Pressure regulator MS2-LR-QS6-D6-AR-MPA-B
The Festo 8086639 is an industrial component from the MS series, size 2, featuring a directly controlled diaphragm regulator with a rotary knob with detent actuator lock and an integrated pressure gauge displaying in MPa. This unit provides constant output pressure with secondary exhausting and a return flow characteristic, operating within a pressure range of 0.1 MPa to 0.8 MPa and a regulation range of 0.5 bar to 7 bar with a maximum pressure hysteresis of 0.025 MPa. It accommodates a normal nominal flow rate of 350 l/min using compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases, weighs 36.1 g, and is rated for a storage, medium, and ambient temperature of -5 °C to 50 °C in any mounting position. Additional verified specifications include a corrosion resistance class of 1, VDMA24364-B1/B2-L LABS conformity, and ISO 14644-1 Class 6 cleanroom suitability.
