Tire Valve

I received a customer valve inquiry this week. I confirmed with the customer that I have purchased this product before. Since the customer knows this product well and introduced it to the customer in detail, the customer also thinks that we are a professional factory. Currently discussing with partners and looking forward to good news from customers!

Copper is the main raw material of the valve, and its content of copper, zinc, lead and iron has strict standards and performance requirements.

Impact of valve price:

Copper analysis, rubber sulfur curve, air tightness test, valve high temperature air tightness test, valve low temperature air tightness test, copper tensile strength, valve bending fracture test, rubber aging test, etc. Mouth is the focus of quality inspection.

First, there is less and less copper and more and more zinc, which reduces the tensile strength and does not meet the standards;

Second, lead and iron generally exceed the standard, even more than 10 times the standard, which can easily cause valve breakage;

The third is that the excessive and instability of the material causes difficulty in the adhesion of the mouth body and the rubber, which is easy to degummed, causing unpredictable consequences.
