For a heating branch with 28mm pipework, this 230V two-port motorised zone valve provides the specified flow-control component. The larger connection distinguishes it from the separate 22mm version in the range. Check the branch’s design flow, valve pressure drop and electrical switching requirements before ordering, particularly when replacing a valve in an existing system.

Frequently asked questions

When would I choose the 28mm valve?

Choose it where the specified valve position has 28mm pipework and the valve meets the design requirements.

Does a larger connection guarantee sufficient flow?

No. Valve sizing and pressure drop must be checked for the actual circuit.

Is it interchangeable with the 22mm valve?

Connection size differs. Any substitution needs the installer’s hydraulic and wiring checks.
