Water Regulations Valve (for RTWA Units Only)

The water regulating valve maintains condensing pressure and temperature
by throttling water flow leaving the condenser in response to compressor
discharge pressure on the RTWA. Decrease the water flow as discharge
pressure falls and increase the water flow when discharge pressure rises.
This valve is not used in cooling tower applications. Cooling towers, however,
may require the use of a three-way bypass valve to maintain balance between
cooling tower water temperature and condensing pressure.
