With the unremitting efforts of nearly 40 years, domestic electric ball valves have made great achievements in the research and development of product types, which is well confirmed by the emergence of EPDM electric ball valves. EPDM electric ball valve was developed to adapt to the popularity of high temperature pipelines. This joint product can effectively adapt to the operating environment of high temperature below 120 degrees Celsius, and basically meet the temperature requirements of conventional high temperature pipelines. Many customers can't really distinguish special materials when they buy electric ball valves, and sometimes they are cheated by bad businesses.
Now many EPDM electric ball valves on the market are EPDM inner rubber layer, and the middle cord fabric and outer rubber layer are common natural valves. This not only has a great impact on the temperature resistance of the electric ball valve, but also has a great impact on its service life! Next, we will analyze the difference between the EPDM electric ball valve (DMEP) and the ordinary natural electric ball valve from several aspects: 1. Observe the color of the ball, that is, carefully observe the color of the valve ball. Many fake products use low-end and inferior quality valves, so the color of the ball produced is often very dark, in order to avoid being seen by experienced people at a glance. Most of them will take black shoe polish to polish them before leaving the factory, making them look black and shiny. However, the electric ball valve produced by the real EPDM valve is pure and slightly dull in color. Not very bright or very dark. 2. Taste, in fact, taste is a good way to judge. Because the components of the valve contain alkene, the valve will have a pungent smell that normal people feel.
However, the EPDM valve is a polymer of ethylene and propylene, and it is a high filling material. Therefore, the EPDM 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. 3. The touch, as for the touch, means that if you carefully rub the inner layer of the valve ball, you will have a smooth feeling. Because the authentic EPDM valve is of good quality and expensive. Therefore, the produced electric valve ball valve is particularly smooth in touch, while the touch of ordinary valves is far from good, and it will feel like touching rough skin.
