What it is

The Drayton 07 05 903 is a 15 mm lockshield valve with an integral drain-off (DO), supplied in a chrome finish. It provides a lockable balancing point on a heating circuit together with a drain-down connection at the same position. The valve carries the manufacturer's DO TP designation.

Before you order

  • Confirm the pipework at the valve position is 15 mm.
  • Check that the drain-off outlet can be reached and that a hose can be routed from it.
  • Confirm the valve orientation suits the pipe run and any nearby obstruction.
  • Establish whether the position needs a lockshield with integral drain-off, or whether a separate drain-off point is already fitted.
