What it is

The Altecnic 3/4 F Double Check Valve DZR Body is a double check valve with a 3/4 inch female connection and a DZR (dezincification-resistant) body. It is manufactured by Altecnic as part of their check valve range and is listed for boiler applications. The valve prevents reverse flow in the pipework, protecting the system and its components from backflow.

Signs this part needs replacing

  • Water passing back through the valve when flow should be stopped
  • Dripping or weeping from the valve body or connections
  • Visible corrosion, pitting or green discolouration on the body
  • Reduced or intermittent flow through the valve
  • Noise or water hammer from the check valve under normal operation

Before you order

  • Confirm the connection size and type match the pipework or fitting it replaces
  • Check the valve is suitable for the system pressure and temperature
  • Verify the valve is being fitted in the correct flow direction
  • Confirm the body material is appropriate for the water quality and installation
