The 11732212 Pro 22 mm 3-Port Mid-Position Motorised Valve is a high-quality zone control valve used in central heating and hot water systems. It is designed to automatically manage and distribute the flow of heated water between heating and hot water circuits from a single valve body.

Function & Purpose

This 3-port mid-position motorised valve controls water flow to the heating circuit, the hot water circuit, or both simultaneously depending on demand from the system controls. 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.

Compatibility

The valve is designed for 22 mm pipework, making it suitable for standard domestic central heating systems. It integrates with common boiler control setups, room thermostats, cylinder thermostats, and programmers typically used in fully pumped heating systems.

Design & Build Quality

The valve features a robust brass body with a reliable motorised actuator for smooth and consistent operation. Internal components are engineered for durability and repeated cycling, while the actuator provides dependable movement and positioning to maintain correct water flow at all times.

Ideal Applications

This motorised valve is ideal for traditional fully pumped heating systems where a single valve is required to control both heating and hot water circuits. It is commonly used in system boilers with hot water cylinders and is suitable for new installations, system upgrades, or replacement of existing 3-port mid-position valves.
