Wheel valves?

My new 107 wheels have 3 valves fitted but one wheel doesn’t have one. Are these pretty standard or are they all TPMS valves?
Either way, how do you fit them??
 
Completely standard valves; the TPMS system uses wheel speed differential to determine whether a tyre is disproportionally deflated compared to the others (so it's a comparative system rather than one that uses predefined pressures like with the valve sensors).

Fitting a standard valve: slight drip of lubricant (dishwasher fluid mixed with water will do) and push the conical bit through the valve hole. It should seat itself and that's it, all done. Removing valves usually involves cutting off the cone that holds them in place.
