A valve that is opened and closed using a solenoid (a cylinder pushing a piston that is electrically or hydraulically powered).
The heater valve is located behind the dash above and to the right of the accelerator pedal. The heater core is right beside it. It is operated by a linkage to the slider on the heater control panel.
Check the vacuum operated valve at the hose going to the heater core.
The heater control valve can stick open or closed, as it is operated by an electrical solenoid. Clean old valve, or a new one. Located under bonnet, near bulkhead
Flare copper pipe and use a flared shutoff valve. If valve isn't flared, use an adapter fitting between copper flared pipe and valve.
This component is electrically operated by the engine computer. It (on most vehicles) changes the oil pressure in the variable valve timing system to adjust the valve timing. It is very similar to the solenoids in use inside an automatic transmission.
