Due to the intensifying market competition, some small electric ball valve manufacturers, in order to reduce costs, have adopted acid and alkali resistant valves in the inner rubber layer of the ball during the production of acid and alkali resistant electric ball valves, while the skeleton layer and outer rubber layer still use ordinary valves. The quality and performance of such acid and alkali resistant electric ball valves cannot be guaranteed, Therefore, our company reminds customers that when purchasing acid and alkali resistant electric ball valves, they must purchase them from regular manufacturers to ensure product quality.
How to distinguish the true and false acid and alkali resistant electric ball valve? First of all, we should observe the color, that is, carefully observe the color of the electric ball valve of the acid and alkali resistant valve. Many low-end fake and inferior products use low-end, inferior quality valves, so the color of the ball produced is often particularly gray. In order to avoid being seen through by experienced people, most of them will take black shoe polish to polish them before leaving the factory, making them look black and bright. However, the acid and alkali resistant electric ball valve produced by the real acid and alkali resistant valve is pure in color, slightly dull, not very bright or dark. Next, you can smell the taste, which is the best way to judge. Because the components of the valve contain alkene, the valve will have a pungent smell that normal people think. However, the acid and alkali resistant valve is a polymer of ethylene and propylene, and it is a high filling material. Therefore, the acid and alkali resistant valve after vulcanization filling has no pungent smell of ordinary valves, but instead has a fragrant smell. So as long as users pay attention, it is not difficult to judge the real good goods.
The skin touch, that is, if you carefully rub the inner layer of the valve ball, you will have a smooth feeling. Because the authentic acid and alkali resistant valve is of good quality and expensive, the produced acid and alkali resistant valve electric ball valve is particularly smooth in touch, while the touch of ordinary valves is far from good, and you will have the feeling of touching rough skin. Our company has many years of production experience, scientific selection of raw material technology and formula, and solid and long-term customer relationship with high-quality products.
