Water-regulating valve is direct-acting and opens on pressure increase to regulate the flow of water or glycol to water-cooled condenser refrigeration systems. Pressure-balanced, modulating valve provides precise control of head pressure on open or closed refrigeration systems.
The water regulating valve, employed with condenser fed with either main or well water, keeps the condensation pressure constant at the previously set value by adjusting the water flow so as to ensure a balanced heat exchange
under all conditions. At plant start-up, this adjustment is designed to allow the thermostatic valve rapidly reaches normal operating conditions and subsequently, during operations, to avoid excessive pressure increases or decreases under different flow conditions. An excessive rise of high pressure affects the refrigerating capacity of the system. On the other side, pressure lowering leads to insufficient refrigerant feeding of the evaporator
with a consequent increased gas overheating and parallel reduction of gas pressure at compressor suction. Castel valves are appropriate for refrigerant
fluids HCFC and HFC and only for main and well water.
