Do You Know Tire Sensor Valve？（Two）

Although the valve mouth is only a small part of the car, it has a great effect on the use of tires and even influence the whole tire pressure monitoring system (TPMS). So we have better pay particularly attention to how to choose tire sensor valve and master the knowledge of tpms valve replacement. This article will continue tell you the difference between different materials of tire valve and show you how to correctly install and replace the valve.

 

 

What Is Steel Tire Valve?

As we had said before, rubber tire valve are cheap in cost and low in tpms valve stem replacement cost, but it is inferior in durability. In order to avoid the aging problem of rubber valve, metal material tire valve has gradually appeared in the market, and steel valve is one of them. Because the material has changed, the price of steel valve nozzle is much higher than that of rubber valve nozzle, the price of a whole set is about 150 yuan, and the price of a single one is about 50 yuan. The service life of the steel valve nozzle is two to three times that of the rubber valve nozzle, which is mainly due to its metal material is not easy to be oxidized, and the metal valve nozzle also has better air tightness. Many tire pressure monitor sensor like to use steel valve as one of its part. But the weight of the steel valve is the heaviest of the three material, heavier then rubber valve and aluminum alloy valve.

 

 

What Is Aluminum Alloy Tire Valve?

Aluminum alloy valve is also belongs to metal valves, its service life and air tightness are equivalent to steel tire valve, but the price is further increased, mainly because aluminum alloy is lighter than steel in weight, which is undoubtedly more good for the dynamic balance of cars’ wheels. The weight of aluminum alloy valve is equal to one third of the steel valve , so this is also one of its advantages.

 

 

Installation Of Tire Valve Nozzles

The installation mode of valve nozzle can be divided into screw type, press type and buckle type. Sometimes we need to replace valve stem on spms sensor and install new one. The rubber valve’s installation is screw type, its valve base has a slot to fix with the wheel ring, which also leads to its use for only one-time, once be removed, the valve can not be used again. To begin valve stem tmps replace, the first step is to remove the entire tire and separate the tire from the wheel ring to reveal the complete valve nozzle. If you choose a rubber valve to install, you need to add some grease to the base before installing the new one to avoid damage to the valve during installation. The installation of metal valve nozzle is a little bit different, you need to screw it and the nut should be tightened with a wrench to ensure that the valve mouth is completely fixed. At last, you should check the air tightness of the tire and then finish replacing the tpms valve.
