Pressure / Temperature

Temperature 80°C (For Water)
Maximum Working Pressure 21 Kg/cm2, Inlet
Pressure Adjusting Range 1 ~ 6 Kg/cm2, 4 ~ 10 Kg/cm2
8 ~ 13 Kg/cm2, 12 ~ 20 Kg/cm2 20 ~ 35 Kg/cm2

Options

  • Available different Models for Air, Water, Oil, Gas, Steam & Chemical
  • LP – Low Pressure Range : 10 – 35 PSI
  • n  HP – High Pressure Range  :
    – Max. Inlet 40 Kg/cm2
    – Outlet 12 ~ 25 Kg/cm2 20 ~ 35 Kg/cm2

Example

  • Pressure drop needed for fully – opened valve. gate for adjustable Pressure range 3 ~ 9 Kg/cm2 of direct activated pressure reducing valve
  • A = B / 4 = 9 – 3 = 1.5 Kg/cm2
  • If the setting pressure of outlet 6 Kg/cm2, Pressure of fully – opened valve gate will be P = 6-1.5 = 4.5
  • Kgf/cm2 (Outlet Pressure should go down under 4.5 Kg/cm2 to make valve gate fully open )
