data-end=\"63\"\u003ePro 22 mm 2 Port Motorised Valve\u003c\/strong\u003e is a high-quality zonal control valve used in central heating and hot water systems. It automatically controls the flow of water through a heating circuit in response to signals from room or cylinder thermostats, enabling efficient heating zoning and system management.\u003c\/p\u003e\n\u003ch3 data-start=\"335\" data-end=\"359\"\u003eFunction \u0026amp; Purpose\u003c\/h3\u003e\n\u003cp data-start=\"360\" data-end=\"768\"\u003eThis motorised valve opens and closes to regulate the flow of heated water in either a heating or hot water circuit. When a thermostat calls for heat, the motorised actuator moves the valve to allow flow; when the demand ends, the valve closes to shut off the circuit. In a two-port configuration, it serves a single flow path, making it ideal for straightforward heating zones or simple hot water isolation.\u003c\/p\u003e\n\u003ch3 data-start=\"770\" data-end=\"789\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"790\" data-end=\"1048\"\u003eThe valve is designed for \u003cstrong data-start=\"816\" data-end=\"842\"\u003e22 mm pipe connections\u003c\/strong\u003e, fitting standard copper or compatible pipework used in domestic and light commercial central heating systems. It integrates with common HVAC controls, room thermostats, programmers, and boiler interlocks.\u003c\/p\u003e\n\u003ch3 data-start=\"1050\" data-end=\"1078\"\u003eDesign \u0026amp; Build Quality\u003c\/h3\u003e\n\u003cp data-start=\"1079\" data-end=\"1357\"\u003eThe Pro 22 mm 2 Port Motorised Valve features a robust body and reliable actuator mechanism built for long-term performance. The motorised actuator provides smooth, quiet operation, while durable internal seals and components withstand continuous duty in regular heating cycles.\u003c\/p\u003e\n\u003ch3 data-start=\"1359\" data-end=\"1377\"\u003eKey Benefits\u003c\/h3\u003e\n\u003cp data-start=\"1378\" data-end=\"1646\"\u003eThis motorised valve allows automated control of heating or hot water circuits, improving comfort and energy efficiency. Its 22 mm sizing makes it compatible with typical central heating pipework, and the motorised action removes the need for manual valve adjustments.\u003c\/p\u003e\n\u003ch3 data-start=\"1648\" data-end=\"1672\"\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp data-start=\"1673\" data-end=\"1982\"\u003eThis valve is ideal for \u003cstrong data-start=\"1697\" data-end=\"1722\"\u003ezoned heating systems\u003c\/strong\u003e, where separate areas of a home or building are controlled independently, or for controlling the flow to a hot water cylinder or specific circuit. It suits new installations, system upgrades, and retrofit projects in residential and light commercial

When heating only is required, the valve directs flow to the heating circuit. When hot water is required, it diverts flow to the cylinder. In mid-position, it allows flow to both circuits at the same time. This ensures efficient system operation and accurate response to thermostats and programmers.\u003c\/p\u003e\n\u003ch3 data-start=\"818\" data-end=\"837\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"838\" data-end=\"1102\"\u003eThe valve is designed for \u003cstrong data-start=\"864\" data-end=\"882\"\u003e22 mm pipework\u003c\/strong\u003e, making it suitable for standard domestic central heating systems.

The two-port design means it controls a single flow path, making it suitable for switching on or off one heating or hot water circuit. Automated operation improves comfort and convenience by eliminating the need for manual valve adjustments. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-start=\"798\" data-end=\"817\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"818\" data-end=\"1133\"\u003eThe valve is designed for \u003cstrong data-start=\"844\" data-end=\"870\"\u003e28 mm pipe connections\u003c\/strong\u003e, so it fits central heating systems that use 28 mm copper or compatible pipework.

When there is a demand for hot water at taps or showers, the valve opens to send water to the hot water circuit. When there is a demand for heating, it switches to direct flow to the radiators. It helps ensure that the right output (heating or hot water) is prioritised according to the current requirement.\u003c\/p\u003e\n\u003ch3 data-end=\"799\" data-start=\"780\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-end=\"1063\" data-start=\"800\"\u003eThe V4043H1056 is compatible with many conventional and system boilers that utilise a diverter valve for heating\/hot water control.

When a call for hot water is detected, the valve actuator shifts to prioritise the hot water circuit. When heating is needed, the valve shifts back to the heating circuit.
