Festo
194671
Pressure regulator LRS-1/2-D-O-DI-MAXI
The Festo 194671 is a directly controlled diaphragm regulator of the D series in the Maxi size featuring a rotary knob with detent actuator lock and constant output pressure with primary pressure compensation, secondary exhausting, and return flow characteristics. This component operates within a pressure range of 1 bar to 16 bar, provides a pressure regulation range of 0.5 bar to 12 bar with a maximum pressure hysteresis of 0.4 bar, and delivers a normal nominal flow rate of 5400 l/min for compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases at temperatures between -10 °C and 60 °C. Designed with a CRC of 2 for moderate corrosion stress and VDMA24364-B1/B2-L LABS conformity, it supports front panel mounting, in-line installation, or mounting with accessories at any position with a product weight of 1610 g.
