The differential bypass valve is used to stabilise the circulation, flow rate and pump pressures in central heating systems. Designed for a quick and simple installation where the valve is set using a visual dial based on your system calculations for the differential pressure. The valve is set by rotating the adjustment dial (with all radiators closed) to the desired differential opening pressure. The valve allows the optimum flow rate through the boiler to be maintained by automatically opening and allowing circulation to continue even if all the thermostatic radiator valves are closed
