The Pro 28 mm Mid Position Motorised Valve (11732213) is a motorised zone valve designed for 28 mm central heating systems. It automatically controls the flow of heated water in response to thermostat and controller signals, allowing water to be directed to heating, hot water, or both simultaneously.

Function & Purpose

This mid-position motorised valve controls water flow based on demand from room or cylinder thermostats and a programmer. It moves to three positions: one for heating only, one for hot water only, and a mid-position that allows flow to both circuits when required. This automatic control enhances system efficiency and helps deliver the right amount of heat where it’s needed most.

Compatibility

The valve is engineered for 28 mm pipe connections, fitting standard domestic and light commercial heating systems that use 28 mm copper or compatible pipework. It integrates with common HVAC controls, room thermostats, cylinder thermostats, and central heating programmers to regulate flow in zoned or multi-circuit setups.

Design & Build Quality

The valve body and motorised actuator are constructed for durability and reliable performance over many cycles. Internal seals and mechanisms are engineered to withstand the pressures and temperatures typical of central heating operation, providing smooth and consistent control of water flow between circuits.

Ideal Applications

This mid-position motorised valve is ideal for fully pumped central heating systems where both heating and hot water circuits need to be managed. It is commonly used in systems with a hot water cylinder and in homes or commercial buildings requiring automated control over multiple circuits.
