The reason for using a water modulating valve is to supply the correct amount of water to the condenser. and to
maintain a proper operating pressure to refrigeration system high side.
The flow of water through the valve is increased as the high side pressure rises and is decreased as high side
pressure lowers.
To calibrate the amount of water flow with the refrigeration system high side pressure, turn adjustment screw
located on end of valve opposite of bellows. Turn screw counterclockwise to raise opening point or clockwise to
lower opening point. Opening point of valve should be set to maintain proper operating pressure in refrigeration
system high side. Refer to Pressure Chart on. Closing point of valve should be set low enough to close valve during
compressor stand–by periods.
NOTE: Cold water will absorb heat faster than warm water. The water flow will therefore automatically
increase as inlet temperature increases.
