ANSI Carbon Steel Wedge Gate Stainless Steel Integral Flange Forged Steel Gate Valve (Z41H-600LB-DN40)

We make every effort to produce and promote Integral forged steel gate valve, API6D Full Bore Ball Valve 1500LB/2500LB, Check Valve, serve the whole country, and go international, making our company a company that the society needs. We carry out perfect testing methods, quick and thoughtful pre-sales and after-sales services. We often carry out extensive technical cooperation and exchanges. We normally follow the basic principle 'Quality Initial, Prestige Supreme'.

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.
