The Myson MPE222 2-Port Motorised Valve is designed for homeowners and DIY enthusiasts managing domestic central heating systems. Its key benefit is efficient control over heating or hot water circuits in fully pumped systems, ensuring optimal comfort and energy use. A minor caveat is its specific suitability for 22mm pipe connections, requiring users to verify compatibility before purchase. This valve offers a reliable solution for directing water flow, featuring a manual override for system maintenance and a clear indicator light when operational.

The valve is supplied with a 1.1-meter length 4-core cable.
It is highly recommended that installation is carried out by a qualified heating engineer or plumber to ensure correct electrical and plumbing connections.
Check electrical supply to the valve. Ensure the system programmer and thermostat are calling for heat/hot water. Verify wiring connections are secure and correct for the system. If issues persist, the valve may require professional inspection or replacement.
Verify power supply to the valve. Check the wiring connections to the indicator light circuit. If the valve is functioning correctly despite the light, the bulb may be faulty. If the valve is not functioning, investigate power or internal valve issues.
Check pipe connections for tightness. Ensure the valve is correctly seated on the pipe. If a leak persists, the valve seals may be compromised and require replacement by a qualified engineer.
Gently try to move the lever. If it remains stuck, do not force it. A qualified heating engineer may be able to free it or advise on replacement.
Compatibility: The Myson MPE222 is designed for use in domestic central heating systems that are fully pumped and utilize 22mm pipework. It is intended as a replacement for similar two-port motorised valves from leading manufacturers.
Setup: Installation should be performed by a qualified professional to ensure correct electrical wiring and plumbing connections. The valve connects to 22mm copper or plastic pipe. Ensure the system is isolated from power before commencing installation. The 4-core cable should be wired according to the system's specific requirements, typically connecting to the heating programmer and thermostat.
Care: Regular maintenance is minimal. Periodically check for any signs of leaks around the pipe connections. The exterior of the valve can be cleaned with a dry or slightly damp cloth. Avoid using abrasive cleaners. Ensure the manual override lever moves freely; if stiff, a small amount of appropriate lubricant may be applied by a professional.
