VALTEC return overflow valves are installed in engineering systems equipped with pumps and are designed to redirect the fluids to the bypass section when the specified differential pressure is exceeded.
Three-way return overflow valve can be mounted on straight or angular section of the pipeline. A meter is mounted to an unused input. The presence of self-sealing connectors (union pipes) on the output makes it possible to install or uninstall the valve at any time.
The use of VALTEC return overflow valves in underfloor heating systems protects the pumping equipment against idol working, as well as the excludes the chances of seizure of circulation through the heat generators and maintains the estimated hydraulic regimen in the circulation system.
Nominal pressure 10 bar. Maximum fluid temperature +120 °C.
