What it is

The Altecnic 1 Threaded BSP (G) Angled Lockshield is the lockshield side of a radiator valve pairing, fitted to Altecnic rad valves. It regulates the flow through the radiator so the system can be balanced, and its shrouded head keeps the set position out of reach of day-to-day adjustment. The angled body pattern suits pipework that approaches the valve from below at a right angle to the radiator tail.

Signs this part needs replacing

  • Weeping or dripping from the valve body or spindle gland
  • Damp staining, scale or corrosion around the valve
  • The valve no longer holds its balance setting
  • A stiff or seized spindle that will not turn
  • Visible thread or body damage preventing a sound connection

Before you order

  • Confirm the thread size and type on the existing valve matches 1 BSP (G)
  • Check that the angled body pattern suits the pipe run to the radiator
  • Confirm the valve is being fitted to an Altecnic rad valve assembly
