Multi-way valve and position controller therefor

摘要

I provide a controller for a distribution valve for a central heating system having a number of sub-circuits, and I also provide a distribution valve for the sub-circuits. The controller has a position sensor for each way through the valve and each position sensor has a selector switch controlled by the position of the valve and a control switch controlled manually or by a thermostat; when for instance the control switch is switched to open the respective valve way, the valve turns until the selector switch signals that the way is open. Any possible way and any possible combination of ways can be opened through the valve, according to the position of the valve.
