Water Automatic Recirculation Valve F51 900 LB API 6D

F51 900LB ARV-Automatic Recirculation Valve
 

EDVC series auto recycle valve is a kind of pump protection device. It automatic protect centrifugal pump when pump body occur cavitation damage or unstable (especially conveying hot water at low load operation medium). Once pump flow is lower than the preseted flow, bypass can completely open to ensure the minimum required flow pump. Even running fully closed, namely running flow is zero, the minimum flow can also pass bypass for auto recycle. Pressure reduced through the multistage bypass pressure reducing valve. EDVC series has big bypass, and this valve is suitable for bypass with big flow, maximum pressure differential is 4MPa, specific choice is determined by factory.
