Automatic Bypass Valve suitable for all heating systems up to 10 bar static pressure where a boiler bypass is required or radiator thermostats are fitted. It provides a simple method of ensuring adequate flow through boilers which require a bypass as well as reducing system noise. In systems fitted with radiator thermostats, the valve opens automatically as the TRVs or zone valves close down and the resistance of the system starts to exceed the preset pressure limit.
Unique and simple adjustment mechanism
High capacity flow up to 83 litres per minute
Wide differential pressure range 0.1 bar to 0.5 bar
22mm Compression fittings for ease of installation
Reduces system noise and maintains an even system pressure
Ensures constant flow through boiler
Lockable set pressure prevents inadvertent adjustment
