Features :

  • Smart Design with High Flow Characteristics Pressure reducing valve can be installed in water supply, air conditioning and fire control systems to maintain the constant outlet pressure.
  • The pressure reducing valve used a sub-valve(pilot valve) to control the main valve. When the outlet pressure reaches the setting range of pressure reducing pilot valve, the pilot valve will automatically sense the outlet pressure and adjusting the pressure of the back pressure chamber in the main valve, so the valve gate can be opened and consequently maintains the outlet pressure.
  • The pressure gauge on the pilot valve shows the outlet pressure. When the outlet opens, the valve of the pressure gauge will decrease.
