You need a Schrader valve.  I got a set of four from my local AutoZone.
Also, get a tool to remove the valve.  You will need to evacuate and refill
the system if you take out the valve unless you have one of the special
tools that allows you to change valve w/o exposing system to atmospheric
pressure.
