GEM-FLOW, G500-PREL, Electric Pressure Reducing 1½"- 4"


G500-PREL model pressure reducing valve is the hydraulic control valve which reduces high upstream pressure value into desired lower pressure value. Control of main valve is achieved by means of built-in solenoid pilot valves. Electric signal for solenoid pilot valves is ensured by means of a control device, time relay, main switch and PLC control units etc. Automated control may be easily ensured by this way in application systems.


  • Use G500-PREL for water distribution, where downstream pressure should be reduced, the valve is commanded to open.
