The Pro Force 3 Port Mid Position Valve is designed for HVAC technicians and homeowners looking to manage water distribution within fully pumped central heating systems. Its primary benefit is the precise control of water flow between heating and hot water circuits, facilitating efficient Y-plan installations. A key caveat to note is that this unit requires professional plumbing knowledge and electrical expertise for safe and correct installation.

No, this is a 3-port mid-position valve specifically designed for Y-plan configurations. S-Plan systems typically use two 2-port valves.
Unless you are a qualified plumbing and heating engineer, it is highly recommended to have a professional install this valve, as it involves both plumbing and mains voltage electrical work.
The mid-position allows water to circulate through both the radiator circuit and the hot water cylinder circuit simultaneously.
Yes, it includes a manual lever that can be used to hold the valve open during system filling or commissioning.
No, this specific model is designed exclusively for 22mm pipework.
Check if the motor is receiving power via the white/grey control wires and verify the thermostat signals.
Ensure the valve is not restricted by airlocks in the pipework and the system is properly bled.
Inspect the wiring connections at the wiring center to ensure the valve actuator is correctly wired to the relevant zones.
For installation, ensure the system is fully drained and isolated from the mains power supply before commencing work. The valve body should be installed in an orientation that allows the motor to be accessed easily for future maintenance. Compatibility is limited to fully pumped systems; do not attempt to install this in a gravity circuit. For care, keep the surrounding area free of debris and periodically check the valve casing for signs of leaks. It is recommended to test the manual override lever annually to ensure the internal mechanism has not seized due to mineral deposits.
