Inta’s automatic differential by-pass valve stabilises the circulation, flow rate and pump pressures in heating systems. The valve can easily be set based on system calculations for the differential pressure and the visual dial on the valve allows for easy adjustment. This allows the optimum flow rate through the boiler to be maintained by the valve automatically opening to by-pass, allowing the circulation to continue even if the thermostatic radiator valves are closed.

• Automatically stabilises flow.
• Protects the pump from pumping against closed head.
• Easily adjustable.
