Feed water flow control valve

Feed water flow control valve Product introduction

China Feed water flow control valvemanufacturer, factory and supplier, Feed water flow control valve can be with electric actuator and pneumatic actiator, which is used in boiler feedwater system to adjust the feedwater flow corresponding to the load or demand, preventing starvation or overflow of the boiler with WCB、 A105、12Cr1MoV、F22、F91、F92、316L,etc, according to different working temprature and pressure.

Feed water flow control valve is important for a feedwater valve to be designed and sized for handling the wide range of severe operating conditions including high pressure drop at minimum flow and low pressure drop at maximum flow. High pressure control valves with anti-cavitation are required for this application. Feed water flow control valve is designed for the full feedwater volume of the steam generator and should produce as low a pressure gradient as possible. With drum boilers, the boiler feedwater control valve must regulate the water level for the drum, and for speed-controlled feed pumps, they must regulate the differential pressure.
