The stop valve on the left picture is a traditional full flow valve while the two right side pictures show the newer quarter turn ball valve type. Quarter turn valves last longer. Traditional full flow valves can be served by replacing the internal rubber O ring. The O ring goes bad due to being compressed, especially if too much force is used twisting the valve to shut the water off. Plumbers now prefer the newer quarter turn valves as they are more reliable.
