What it is

The Altecnic 3/4 F Single Check Valve DZR is a single check valve with a 3/4 inch female connection, manufactured by Altecnic for use in heating and boiler installations. It permits flow in one direction only, preventing backflow within the circuit. The body is produced in DZR (dezincification-resistant) brass for service where water conditions would attack standard brass.

Signs this part needs replacing

  • Water passing back through the valve when flow should be stopped
  • Continued flow in the reverse direction after the pump or supply is shut down
  • Dripping or weeping from the valve body or connections
  • Reduced flow or chatter through the valve
  • Visible corrosion or dezincification of the brass body

Before you order

  • Confirm the connection size and gender required: 3/4 inch female
  • Check whether a single or double check valve is needed for the application
  • Verify the valve is being fitted in the correct flow direction for the circuit
  • Consider whether DZR construction is required for the system water conditions
