FV:
Manually lock the valve, high pressure resistance, smoother air leakage linearity, thin valve base, small diameter of the valve, less impact on the strength of the rim, you can use 19C size inner tube or narrow ring,the price is high!
AV:
AV is mainly locked by the internal pressure top force, high pressure resistance, and the air leakage linearity is steep, that is to say, when the air pressure is not enough, the air leakage is faster, the base of the air nozzle is large, and the diameter of the air nozzle is also large, but the inflation flow is large, so it is widely used. It is used in inner tubes with large air volume, so it is very convenient to inflate!
EV:
The EV is leak proof by the rubber sleeve. The leakproof ability mainly depends on the quality of the rubber sleeve.
The air tightness is very good, but the pressure resistance is low, the valve base is large, the weight is large,
the inflation flow is small, and the durability of the rubber sleeve is poor.
The inner tube will be scrapped due to valve problems, and the price is low!
