Pro Motorised Valve - 22mm

This valve is a mid-position (Y-plan) valve, suitable for two- and three-port heating setups and compatible with most standard domestic central heating systems.

No, the valve uses 22mm compression fittings, which allow for quick and leak-free installation without the need for soldering.

Regular visual checks for leaks and dust build-up are recommended. The actuator head is designed for easy replacement if it fails, extending the valve's lifespan.

Please refer to the product packaging or manufacturer's documentation for specific warranty details, as these can vary.

While the actuator head is user-replaceable, replacing the main valve body is a more complex task that typically requires a qualified heating engineer.

A mid-position valve operates in three states: fully open to heating, fully open to hot water, or closed to both. This allows for efficient control over which circuit receives hot water.

The Pro 22mm Motorised Valve is designed for compatibility with most major boiler brands and standard wiring centers.

Check that the power supply to the valve is connected and functioning. Verify wiring connections against the system diagram. Ensure the thermostat is calling for heat or hot water.

Turn off the system water supply. Gently tighten the compression nuts. If the leak persists, the pipework or valve seal may be compromised and require professional inspection.

A slight humming noise during operation is normal for motorised valves. If the noise is excessive or unusual (e.g., grinding), the actuator may be faulty and require replacement.

Ensure the valve is correctly positioned for your system's requirements (e.g., Y-plan). Check that there are no blockages in the heating system. Verify that the thermostat settings are correct.
