Energy Fluid Technology Solution | delan MX2500 Series Valve Characteristic Typical Application Minimum flow circulation valve is the key supporting equipment of power plant’ s boiler feedwater pump. Boiler water from the feedwater pump will be pressurized up to 20-30Mpa or above in the deaerator then sent to the high pressure heater and eventrally into the boiler. A certain minimum flow quantity of the feedwater pump should be ensured to take away the heat generated by its operation so as to avoid overheating and damage of vanes due to cavitation. Boiler feedwater flow is small during the startup...
