Inta 28mm Automatic Bypass Valve

The Inta automatic bypass valve is a differential pressure valve for wet heating systems. It opens automatically as system pressure rises when thermostatic radiator valves or zone valves close, so water keeps circulating through the boiler or heat pump and the pump isn't left running against a closed head. The opening point is set on a visual dial on the valve body. Choose the straight (in-line) ABPS28CP or the angled (90°) ABPA28CP to suit your pipe run.

Key points

  • Automatic differential pressure bypass, no electrical connection needed
  • Adjustable setting 0.1 to 0.5 bar with a visual dial
  • Stabilises circulation, flow rate and pump pressure
  • Protects the pump and maintains minimum flow through the heat source
  • 28mm compression connections, straight or angled pattern

What's included

  • 1 x Inta 28mm automatic bypass valve in your chosen style

Installation and compliance

Fit across the flow and return between the pump and the first TRV or zone valve, in line with the flow direction marked on the valve, and set the dial to the differential pressure from your system calculation. Install to the manufacturer's instructions and the boiler or heat pump manufacturer's minimum flow requirements. Installation should be carried out by a competent heating engineer.
