This really is known as a “globe valve” in engineering and, although it provides a leak-proof seal and good fine adjustment of flow, both rubber washer and also the valve chair are susceptible to put on (but for the chair, also corrosion) with time, to ensure that eventually no tight seal is created within the closed position, producing a seeping tap. The washer could be changed and also the valve chair resurfaced (a minimum of a couple of occasions), but globe valves will never be maintenance-free.
