Just suck or squeeze. And they don't leak when you're not doing either. Took some getting used to.
There's also a twist thing that locks things shut when you're not riding.
The lock is one reason I like them for touring. I keep one in my tent. Don’t have to worry about getting water in the tent if I roll over and put pressure on it while sleeping.
