High Temperature Tesistance of Stainless Steel Flange Gate Valve

In pursuit of low price, high efficiency and fast speed, we pay more attention to quality assurance and strive to do every A105 Bolted Bonnet Forged ANSI gate valve, API 602 Forged Gate Valve, pressure seal gate valve 2500lb well for customers. We've been strict with every part of our work. Our company owns a wide range of upstream and downstream resources in the industry. We believe that creating new value is also our social mission, and we will work hard with this mission.

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.
