V4043 Motorised Zone Valve

 

The V4043 series of two port Motorised Valves has a wide range of flow control applications in domestic and light commercial central heating systems. The V4043H normally closed models have end switches for electrical control of pump and/or boiler. The V4043B normally open model is particularly applicable to control of solid fuel systems, since it will always fail-safe in the event of a power failure.

  

Features

  • Motor open
  • Spring return action
  • Manual lever for filling & draining the system
  • Powerhead replaceable without draining down
  • Potential free end switch for electrical control of pump and/or boiler
  • Quiet operation, minimal power consumption

  

Options

  • Normally open & normally closed versions available
  • 22mm/28mm or 1/2", 3/4", 1" BSP connections
  • Replacement motor/powerhead/ball and 'O' ring kit
