What it is

The Drayton 07 91 011 is a Tapstat conversion head supplied as a MK3 to MK4 conversion. It is the sensing head component of the Drayton Tapstat valve range, allowing an existing MK3 installation to be brought up to MK4 head specification. It sits within the valves category of heating controls and is supplied by Drayton under part number 07 91 011.

Before you order

  • Confirm the existing Tapstat valve is an MK3 unit that is to be converted to MK4 head specification.
  • Check the part number on the existing head or valve body against 07 91 011 before ordering.
  • Confirm whether the conversion requires the head only or a complete valve assembly for the installation.
  • Note the MK3 to MK4 designation, as this head is specific to that change of specification.
