It have the function of regulating the negative vacuum pressure, keeping it stable at set value regardless of flow and variations in the degree of vacuum in the primary network. The units are of a double diaphragm construction and have been designed to exploit to their advantage any existing pressure differential between the Ordering code 171S2B000V 3, 4 7 74 3, 1 21 02 531 G1/4" 26 G1/8" M4 45 M30x1.5 01 562 45 G1/4" G1/8" Example: 171S2B000V Regulator for vacuumG1/4" Flow rate chart Adjustment characteristic 80 70 60 50 40 30 20 10 0 0 20 40 60 80 100 120 140 160 180 Vacuum (-kPa) Flow rate (Nl/min) 60 70 40 50 20 30 10 0 35 40 45 50 55 60 65 70 75 80 85 10 Nl/min Input vacuum (-kPa) Regulated vacuum (-kPa) Regulator for vacuum secondary depression and atmospheric pressure. The degree of vacuum is obtained by rotating the adjusting knob, rotating it clockwise to increase the amount of vacuum and anti clockwise to decrease it. They are used in all centralized systems where regardless of the vacuum in the main network a lower vacuum level is required for other applications.
