An automatic recirculation valve (ARC valve) is a multifunctional valve whose primary purpose is to ensure that a pre-***ermined minimum flow
is assured through a centrifugal pump at all times. This is important as centrifugal pumps suffer from overheating and cavitation and can
be permanently damaged if they run dry.
Through many years of research and development,continuous innovation and practice, shanghai datian valve Co. research ZD series Automatic recirculation control
Valve, to prevent overheating, serious noise, unstable and erosion damage of centrifugal pump under low load operation. As long as the flow rate of the pump valve below a certain value, the bypass backflow mouth will automatically open to ensure necessary minimum flow of pump.

¡ö Centrifugal pumps require protection
If you use centrifugal pumps for any liquid-boiler feed water, condensate, or process fluids, a significant investment has been made in the pump, driver and related controls. Minimum flow protection is vital upon pump start up and low demand conditions. If reliable protection does not exist, the following unfavorable effects can interfere with the performance and reliable operation of the pump.
The liquid¡¯s temperature will rise due to friction and hydraulic losses within the pump. Figure 2a illustrates the temperature rise in relationship to the H-Q curve. The curve indicates that at or near the best efficiency point,the temperature ris |
