What it is

The Altecnic 42mm Ball Valve with Red Lever Handle is a quarter-turn isolating valve from Altecnic's ball valve range. It is operated by a red lever handle and is used to shut off flow through a pipe run on heating and boiler systems. The ball valve design gives a full-bore, low-resistance path when open and a positive shut-off when closed.

Signs this part needs replacing

  • The lever turns but flow is not fully shut off when the valve is closed.
  • Water weeps from the spindle or gland area around the lever stem.
  • The lever is stiff, seized or fails to move through its full quarter turn.
  • Visible corrosion or scale build-up on the body or connections.
  • Persistent dripping from the valve body or joint faces.

Before you order

  • Confirm the pipe size is 42mm before ordering.
  • Check the connection type and thread or fitting arrangement on the existing valve.
  • Confirm the valve orientation and that a lever handle will clear surrounding pipework.
  • Verify the system is depressurised and drained before removal and fitting.
