What it is
The Honeywell DU145-3/4B is an angled automatic by-pass valve supplied with 22mm compression connections. It is a differential by-pass valve that maintains a minimum flow of water around a heating circuit when thermostatic radiator valves or other zone controls close down, limiting the risk of reduced flow through the boiler and pump. The angled body allows the pipework to be taken away at 90 degrees to the inlet.
Before you order
- Confirm the valve is 22mm compression at both connections and matches the pipework at the installation point.
- Check that the angled body will suit the pipe run and available space before ordering.
- Verify the part number DU145-3/4B against the valve being replaced or the system documentation.
- Confirm the by-pass setting required by the boiler or system manufacturer is achievable with this valve.
