Model Number: YCAT-150LB-#6759 Brand Name: YI CHEN Key Specifications/Special Features: YI CHEN automatic recycle valveIntroductionYCAT series automatic 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 presented 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 automatic recycle. Pressure reduced through the multistage bypass pressure reducing valve.YCAT 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.CharacteristicsSimple structure, operation reliable and stabile, with few movement parts.Be easy for installation, can be installed vertically or horizontally on pump pressure outlet.Bypass flow is large, maximum flow is 60% of main flow, KV value can be adjusted.Maximum bypass operating pressure differential is 4MPa. Bypass non-return function is optional.Applicable medium including: water, oil, methanol and other liquid medium.Working temperature is from -196°C to +300°C.Diameter and pressure range
Valve body type: three-way casting valve
Nominal diameter: DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400
Nominal pressure: PN 16, 25, 40, 64, Class 150, 300 L
Connection type: flange FF, RF, RTJ, BW, SW
Working principle
According to the difference of inductive main flow, main valve disc check cone of Automatic Recycle valve will automatically move to a certain position. At the same time the main valve disc drive bypass valve stem, transfer the movement of main valve disc to bypass, through control bypass valve disc position, change bypass throttling area, so as to control bypass flow. When main valve disc back into valve seat closed, all flow backflow through bypass. When main valve disc to rise to top position, bypass is fully closed, all the flow of pump flow to process system. This valve set four functions in one body.
Flow perception: automatic recycle valve main valve disc can automatically perceive main flow of process system, thereby according to the flow to determine position of main valve disc and bypass disc.
Recirculation control: automatic recycle valve can inhaled pump normal operation required minimum flow into storage device through bypass, so as to adjust pump H - Q characteristics, to realize recycling.
