But a gate valve just regulates the flow, a stoptap stops it, hence the name.
Gate valves are for where you need a lower flow resistance than a tap when they're turned on, they'll just drip if you use them as a stop tap. If you have tanked hot water and low pressure (I don't), then the low resistance of a gate valve might be advantageous, but that still leaves you with the dripping when it's off.

A gate valve is NOT a regulator,it is it is a ON/off(service valve),Unless it is a Lockshield Gate Valve.
And should be used on all hot water flow pipes,as they are full bore valves,and a Stop is not full bore.
They only drip if you use cheap valves,same as cheap Ballofix(type) valves @70p each,and these also are not Flow Regulators.
