Product Description

Vatac Automatic Recirculation Valve is a kind of pump protection device. It automatic protect centrifugal pump when pump body occur cavitations 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 reducing valve.
 
Vatac Pump Protection Valve is suitable for bypass with high pressure differential, maximum pressure differential is 30MPa, and specific choice is determined by factory. Multistage decompression type M type bypass can eliminate noise made by high-speed flow medium; prevent damage of cavitations erosion and braising to valve components.

Vatac Pump protection valves (automatic recirculation valve) are with main features as below:
» Nominal Diameter: 1"~12"
» Engineering Pressure: CL150~900
» Bypass Size: 1/2DN (standard); or special
» Recommended Flow Rate: 4 to 6 m / s up to 8 m / s
