Feed water control valves are one of the most important control components of the water-steam circuit. The valve controls the supply of feed water to the boiler. The valve’s requirements are high. The pressure drop across the valve should be minimized, but still give a l good control characteristic. A main feed water control valve is designed for the total flow of the steam generation at low differential pressures. The start-up valve however, is used for low flows and high pressures.

Advanced Valve Solutions also provides a special design feed water control valve which gives us the opportunity to combine the start-up and main feed water control function in one valve. A decisive cost benefit for our customers!
