DK32 - DK34 - DK37TECHNICAL DATA 77.5 Differential pressure regulatorsDifferential pressure regulators are used (DK32 and DK37 only) to help maintain constant flowrates in the case of fluctuating inlet or outlet pressures. Minimum pressure levels are requiredto permit operation of the regulators (see Regulator characteristics).Differential pressure regulators are not pressure reducing valves!1 Inlet pressure regulators, types RE, NREThe regulators maintain a constant flow rate at variable inlet pressure and constant outletpressure.Example: Inlet pressure regulator RE-1000: Current flow rate: 1000l/h airConstant outlet pressure 1.013 bar abs.p2:With a variable inlet pressure greater than 0.5 bar the flow rate in the device is constant.2 Outlet pressure regulators types RA, NRAThe regulators maintain a constant flow rate at constant inlet pressure and variable outletpressure.In order to function, there must be pressure difference between the inlet pressure andthe outlet pressure. The inlet pressure p1 must always be greater than the outlet pressure p2.Example: Outlet pressure regulator NRA- Current flow rate:800l/h air800Constant inlet pressure: 6 barWith a variable outlet pressure of 0...5.5 bar the flowrate in the device remains constant.Regulator characteristics1 Inlet pressure regulators, types RE andNRE2 Outlet pressure regulators, types RA andNRA07/2009 - 4000287102 MA DK32-34-37-R04-enwww.krohne.com35
