Honeywell 28mm Two Port Zone Valve V4043H1106/U

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
