A full bore lever valve yes stopcock no bud
Have to agree with Shaun, there's nothing wrong with it being there - just not good practice. A stop tap is going to restrict the flow a lot more than a gate valve or full bore level/butterfly valve.they both do the same job no difference in my eyes
No valve should be fitted on the outlet
