What is the difference between a service and isolation valve?
What is the difference between a service & isolation valve? Service & Isolation valves are an essential part of a bathroom suit.

Where should a service valve be located to isolate the hot water supply from the hot water storage vessel to the taps is it the primary return or primary flow or cold feed or open vent?
The isolation valve should (must) be placed on the cold water side (and/or the return side), entering the water heater. Placing the isolation valve on the hot or outlet side of the water heater has the potential of creating a bomb.

EXACTLY
What is an isolation valve and fill valve in a toilet?
An isolation valve isolates the fixture so one can disassemble the fill valve (ball -cock) and make necessary repairs. Also the isolation valves on most fixtures are globe pattern type so one can throttle the volume entering the fixture to prevent hydraulic shock and prevent excessive noise

What is a refrigeration queen valve?
A queen valve is the service valve (isolation valve) located at the inlet of the liquid receiver (between the condenser outlet and the liquid receiver). The king valve is the service valve at the outlet of the liquid receiver (between the liquid receiver and the liquid line). Queen valves seem to be in use much less than king valves.
