The orifice must be selectedso that, on the one hand, the desired flow range isreached, and, on the other, that a sufficient proportionof the total pressure loss takes place over thevalve when fully opened. Guide value: ∆p Valve > 30%of the total pressure.Make use of the consultation of our Bürkertengineers as early as possible in the planningphase.Maximumpressure[psi]Maximum coilcurrent[mA]Powerconsumption[W]Type 2821 0.8 NPT 1/8 0.021 19 174 185 4 164 568A proportional 1.0 NPT 1/8 0.029 27 145 185 4 164 569valve NC 1.2 NPT 1/8 0.046 43 116 185 4 164 5701.6 NPT 1/8 0.058 54 87 185 4 001 555Type 6022 2.0 NPT 1/4 0.116 108 116 300 8 456 967A proportional 4.0 NPT 1/4 0.383 356 29 300 8 456 968valve NCItem no.Proportional Valves/Mass Flow Controllers and MetersType 6023 4.0 NPT 3/8 0.464 430 58 530 15 456 965A proportional 6.0 NPT 3/8 0.812 750 29 530 15 456 966valve NCSubject to modifications
