Water regulating valves, usually used with condensers fed with either mains or well water, keep the condensation pressure constant at a pre-set value by adjusting the water flow so as to ensure balanced heat exchange under all conditions. At plant start-up, this adjustment is designed to allow the thermostatic valve to rapidly reach normal operating conditions and subsequently, during operations, to avoid excessive pressure increases or decreases under different load conditions.
Accessories for use with the following ASHRAE 34:2019 refrigerants, Class A1:
Maximum allowable pressure of the refrigerant 22 bar.
Maximum allowable temperature of the water +80 °C.
