Carbon Steel Wcb 150lb 2PC Flanged Ball Valve

We rely on years of manufacturing experience and deep understanding of the ASME Class 150/300/600 Gate Valve, Single Action Pneumatic Globe Valve Pn25, API6D Full Bore Ball Valve 1500LB/2500LB industry. Our company takes the user first as the purpose, meets the needs of customers by providing professional products and services, and creates greater value for them, so as to realize the win-win situation between the company and customers. The support, trust and dependence of customers are our driving force for continuous progress.

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 eventally 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 and shutdown process while the water demand decreases in condition of breakdown. In order to ensure the normal operation of the pump, a recirculation system should be mounted in the pump outlet to carry a portion of the feedwater back to the deaerator from the pump.
