● Factory preset enables reduction of pressure adjusting time in the assembly process. No adjustment of downstream pressure is needed. ● Tamper-proof – prevents unwanted adjustments. There is no pressure adjusting screw nor knob. ● The body volume is reduced by 33% compared with the RVUP model. Medium : Air ● Operating pressure : Preset pressure~1.0 MPa ● Operating temp. : 0~60ºC (No freezing) ● Pressure tolerance : ± 0.025 MPa (When preset pressure+0.3 MPa is supplied)
