Actually the printing color of the valve is not related to the quality of the product. The printing of the valve is only for enterprises to mark their own products, which make their products have an independent mark, so that they can be better identified in after-sales service and publicity!
The reason why customers are so puzzled is that, to a certain extent, some companies in the market used relatively low-end sales methods: if they use white checking valve , they say while color is better. ; If they use black check valve , they say black is better .
In fact ,the color of the valve is not related to the quality of the airbag packaging. Regardless of the green , black label, and white check valve film, if it is a low-end bargain, any color is useless. Raw materials follow the business rule of "one penny for its value ".
