What it is

The Altecnic 3 Port Valve With 9.0 Kv 1 is a three-port valve used to divert or blend water flow within a heating circuit. It carries a Kv rating of 9.0, which describes its flow capacity through the valve. It is listed by the manufacturer against Altecnic ball valve assemblies and boiler-side applications.

Signs this part needs replacing

  • Water weeping from the valve body, spindle or port connections
  • The valve no longer diverts flow correctly, leaving one circuit cold while another overheats
  • The actuator runs but the valve does not change port position
  • The valve is stuck open on one port, causing continuous flow in the wrong direction
  • Stiff or seized operation at the spindle or lever

Before you order

  • Confirm the existing valve is a three-port type and check the port connections match before ordering
  • Check the system requires a Kv rating of 9.0 for correct flow through the circuit
  • Establish whether the valve body, the actuator or the complete assembly needs replacing
  • Note the product reference 644366 when enquiring
