Looking into my heating cupboard at home, I see at least four types of VALVE in use.  The one on the top of my pressurised hot water tank controls the cold water feed from the mains, is a 15mm diameter ball valve with a handy quarter-turn lever.  This is a quick shut-off valve that controls the whole hot water supply.  I also see lots of  in-line ball valves under each basin with screwdriver actuation that act as isolators for each tap
