• Direct Industry Compatibility: Serves as a high-performance cost-effective replacement for industry-standard 22mm zone valves including the V4043H series
• No-Drain Maintenance: Features a detachable actuator powerhead that allows for quick motor replacement without the need to drain your entire central heating system
• Standard 22mm Compression: Designed with precision 22mm fittings for seamless connection to UK copper or plastic pipework in domestic S-Plan and Y-Plan setups
• Integrated Control Switch: Includes a built-in auxiliary microswitch and 1-metre 5-core heat-resistant cable for efficient boiler and pump signal management
• Reliable Fail-Safe Action: Utilizes a robust spring-return mechanism to ensure the valve fails to a closed position during power loss preventing unintended heat flow
• Pro-Installation Standards: Engineered for horizontal or vertical mounting to meet professional plumbing standards provided the head is never positioned below the pipe

The LavaTap 2 Port 22mm Motorised Valve is a professional-grade solution for controlling water flow in domestic central heating and hot water systems. This complete valve and actuator unit is engineered to provide a reliable, long-term alternative to expensive brand-name replacements. It features a high-torque motor and chemical-resistant internal seals to ensure smooth operation even in older systems where debris may be present.

Compatibility and Replacement Details This unit is a direct functional replacement for the industry-standard Honeywell V4043H series and serves as a high-quality alternative for Danfoss HPA2 system setups when replacing the complete valve. It is designed specifically for "S-Plan" and "Y-Plan" central heating systems to provide precise zone control. The valve features standard 22mm compression fittings, making it compatible with all standard UK copper and plastic pipework.

Technical Specifications Designed for UK mains systems, this valve operates on a 230V AC (50Hz) supply with a highly efficient power consumption of only 6W when energized. Each unit is supplied with a 1-metre 5-core heat-resistant cable, allowing for seamless integration into existing wiring centers. The built-in auxiliary microswitch (rated at 2.2 Amps) provides the necessary signal to fire the boiler and pump once the valve has reached the fully open position.

Installation and Return Prevention To ensure a successful installation and avoid common errors, please verify your system requirements before purchase. This is a 2-port valve for 22mm pipes and is not a 3-port mid-position diverter. During installation, the valve can be mounted horizontally or vertically, but the actuator head must never be positioned below the level of the pipework to prevent electrical damage from potential leaks. We highly recommend flushing the heating system and using a chemical inhibitor before fitting to prevent internal debris from jamming the valve seat.
