Low-load start-up control valves are designed to supply the boiler with the exact volume of feedwater required during start-up (approximately 30% to 50% of the full-load water volume). This flow is control-regulated at higher differential pressures than those encountered during full-load operation. The system must reliably handle even small partial volumes at high pressure drops and extensive turndown ratios. The exact same requirements apply during low-load operations.
