Quickly responds to changes in water volume! An automatic secondary pressure regulating valve that maintains stable performance over the long term.
The "RB-QM type" is an automatic secondary pressure regulating valve that utilizes the water pressure on the inflow (primary) side and outflow (secondary) side to quickly respond to fluctuations in primary side pressure and changes in secondary side water volume, operating smoothly and gently while maintaining a stable set water pressure on the secondary side. This method is carried out by controlling the differential pressure of the main valve's piston, allowing the secondary side water pressure to be easily set to any desired pressure within the range of pressure reduction by adjusting the pilot valve. 【Features】 ■ Developed specifically for small-scale water supply systems ■ Double function of main and auxiliary valves ■ Operates solely on water pressure ■ Prevents water hammer ■ Easily adjustable secondary side water pressure on-site *For more details, please refer to the PDF document or feel free to contact us.
