I have used many complex bite valves, particularly Nathan's rotary valves, as well as simpler bite valves and bowls. The complex ones are too bulky to mess around with on the track, especially when running in 20 degrees with gloves on. The simple ones drip, flow, and can freeze in the cold, causing you to bite harder and gnaw through the shell faster. This simple switch is a good compromise. It securely closes the valve, which is easy to check (no need to read "open" and "close" on the plastic stampings during operation) and reduces dripping.
