Pressure reducing valve can prevent pipeline
breakage due to high pressure.
Pressure reducing valve can be installed in water
supply pipeline and maintains the setting pressure in
main valve outlet, regardless of the difference in the
inlet pressure.
Pressure reducing valve can be installed in water
supply, air conditioning and fire control Systems to
maintain the setting pressure in outlet.



 
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 chamber pressure in the main valve, so
the valve gate can be opened and consequently the
outlet pressure can be maintained.


‧Adjustment Range :
 0.2kgf/cm2 ~7kgf/cm2
‧Special orders can be arranged for higher
 pressure adjusting range.
‧In the case of high pressure, valve body
 made by stainless steel is recommended.

‧The pressure gauge on the pilot valve indicates the pressure in outlet.
 The indicating value will be lower when the outlet is in open state.
‧When large flow rate is implemented in outlet, or when the gate is switching off rapidly and waiting the
 response of pilot valve to close the main valve gate, delayed response might happen. At this time the outlet
 pressure will rise a little, and a small pressure relief valve can be added to the outlet.





‧Special order is needed for size over 14" or
 particular dimension.
