ALVE
The reason for using a water modulating valve is to supply the correct amount of water to the condenser to maintain
the proper operating pressure in the refrigeration system high side. The flow of water through the valve is increased
as the high side pressure rises and decreases as high side pressure lowers.
Figure 4. Adjustment Screw
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 See Figure 4. Turn screw counterclockwise to raise opening point. Opening point
of valve should be set to maintain proper operating pressure in refrigeration system high side. Refer to Pressure Chart
on Page 10. Closing point of valve should be set low enough to close valve during compressor stand by periods.
NOTE: Cold water will absorb more heat faster than warm water. The water flow will therefore auto-
matically increase as inlet temperature increases.
