22mm Straight Bypass Valves
Automatic differential bypass valves are designed to stablise the circulation, flow rate and pump pressures in heating systems. The valve can easily be set based on system calculation for the differential pressure and the visual dial on the valve. This allows the optimum flow rate through the boiler to be maintained by the valve automatically opening to bypass, allowing the circulation to continue even if the thermostatic radiator valves are closed.
Valves for use on heating systems where control is by zone or thermostatic radiator valves
Fitted between flow & return permitting circulation through boiler and helps prevent unnecessary cycling of boiler
