Description

The AR Valve’s main purpose is to ensure that a pre-determined minimum flow through a centrifugal pump is guaranteed at all times. This is important because centrifugal pumps operating below the minimum flow suffer from overheating, vibrations and cavitation and can be permanently damaged and even completely destroyed if they run dry.

FEATURES

• Highly flexible application range
• Experienced, robust design
• Accelerated shut-off to avoid cavitation by critical operation
• Intergrated non-return function in the bypass
• No additional back-pressure regulation required
