ZDT Series Automatic Recycle Valve(ARC 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 Automatic
Recycle. Pressure reduced through the multistage bypass pressure
ZDT series Automatic Recycle Valve has big bypass, and this valve
is suitable for bypass with big flow, maximum pressure differential
is 4MPa, specific choice is determined by factory.
- Simple structure, operation reliable and stabile, with few movement
- 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
Working temperature is from -196℃ to +300 ℃
