Product accent:
  • Pressure reducing valve can prevent pipeline breakage due to high pressure.
  • Pressure reducing valve is installed in water supply pipeline and maintains the setting outlet pressure in main valve, regardless of the different inlet pressure.
  • Pressure reducing valve can be installed in water supply, air conditioning and fire control systems to maintain the setting outlet pressure.
   

Valve Action Description

Valve Action Description
The pressure reducing valve uses a sub-valve (pressure reducing pilot valve) to control the main valve. When the outlet pressure reaches the setting rang of pressure reducing pilot valve, the pilot valve will automatically sense the outlet pressure and adjust the pressure of the back pressure chamber in the main valve, so the valve gate can be opened and consequently maintains the outlet pressure.
  • Outlet Pressure Adjusting Range:
    1 kgf/cm2 ~7kgf/cm2
    2 kgf/cm2 ~10kgf/cm2
    4 kgf/cm2 ~12kgf/cm2
  • Higher pressure adjusting range upon request.
  • Medium : Non-Corrosive Fluid
  • Applied Temperature: -15℃~80℃
  • Test Pressure / Working Pressure
              Cast Iron: 21 kgf/cm2 / 12 kgf/cm2
          Bronze: 21 kgf/cm2 / 12 kgf/cm2
      Ductile Iron: 32 kgf/cm2 / 20 kgf/cm2
          Stainless Steel: 32 kgf/cm2 / 20 kgf/cm2
  • It is suggested to use Stainless steel material body for higher pressure

【Attention】
  • The pressure meter on the pilot valve shows the outlet pressure. When the outlet opens, the value of the pressure meter is lower.
  • When the outlet is used for large flow and the gate generates quick-close motion, the pilot valve will slowly respond to the main valve to close the gate. Under this situation, the outlet pressure gets a little higher, and a tiny pressure reducing valve can be added.
