Just in my experience those gate valves never fully close off the

Yup. After about 20 years of never being used, mine barely made any
difference. And then discovered the brass to steel action between one of
them and the pump had seized the cap nut solid. So had to cut it off. The
new pump - although the same make, and nominally the same model, in
combination with the new valves, was somewhat sorter overall, meaning I
had to extend the pipework. So much for a ten minute job. :-)
