Description:
Castle Pressure Independent Control Valves are advanced flow control devices designed to maintain a constant flow rate regardless of pressure fluctuations in HVAC and chilled water systems. These valves combine the functions of a control valve, balancing valve, and differential pressure controller in one compact unit. They ensure accurate temperature control, energy efficiency, and simplified commissioning, making them ideal for modern building automation systems.
