Automatic Recirculation Valves

Automatic Recirculation Valves for Increased Safety and Efficiency
Our automatic recirculation valves are designed to enhance the reliability and efficiency of your fluid systems. Their innovative design ensures optimal performance, helping to reduce costs and increase productivity across your operations.
Automatic Recirculation Valves: Reliable Safeguarding for Your Pumps
Automatic recirculation valves, also known as minimum flow valves, provide essential benefits for the operational safety of liquid systems. They ensure a consistent minimum flow rate, effectively protecting pumps from cavitation, overheating, and damage. Designed to withstand extreme operating conditions within a temperature range of -10 °C to 200 °C, these valves help extend pump service life, reducing maintenance costs over time.
Operating under the control of its own media, the valve minimises the need for manual intervention, enhancing efficiency and reducing downtime. By keeping the pump within its optimal operating range, the valve not only prevents potential damage but also improves overall system performance and energy efficiency.
