Medium controlled recirculation valve

The application of the medium controlled re-circulation valve is to protect the pump against 
damage during low load. Automatically the bypass opens when the flow through the pump
reaches a minimum flow. The medium will be bypassed to prevent the condensate from heating up, which would lead to cavitation. Therefore, the minimum flow valve has the function of a pump safety valve.

Design characteristics:
- maintenance friendly due to easily    exchangeable internals
- Few wear parts
- no cavitations due to safe pressure reduction in the bypass line.
- Customised design according to the pump specification
Three functions in one valve!
- Non return function for pump protection
- Recirculation flow for low load
- Pressure reduction in the bypass line
