The Honeywell 40003916 Powerhead enables a complete powerhead to be replaced without the need to drain down the V4043H valves. On older valves which pre-date 1985 the head cannot be replaced, the adaptor plate assembly can be used to upgrade the valves which in turn allows the replacement powerhead to be fitted.

Features and Benefits:

  • One type of powerhead for the separate valve series.
  • No need to drain down the valve.
  • Suitable for use with V4043H-series Honeywell valves.
