Here are some main brief installation points of spring relief valve or spring safety valve we need to notice. Before installing spring relief valve, the first thing we need to pay attention to is to be sure to test the seal performance. If the relief valve leaks or the air cushion is broken, they are needed to be changed immediately accordingly. Then, it can be got the best use by all of us. The first premise is that the vertical installation is needed to be paid attention to for all parts of the relief valve in the process of relief valve installation. And, the installation angle should be precise and formal. Of course, tools should be used to make the corresponding auxiliary. Then, it can make the whole installation process smoothly and effectively. Second, it should be noticed that it is not allowed to give pressure on the exit of the relief valve during the installation of relief valve. It’s better to let it empty directly so that the relief valve can work effectively. Then, people can get it best effect, have better use experience and install the relief valve in place. Third, it should be noticed that the operator had better wear the corresponding gloves tools on their hands to avoid that oil pollute relief valve. The oil pollution can affect the sealing effect of relief valve. At same time, it also may lose the whole service life of the relief valve. Therefore, it is a good way to let the operator wear the gloves tools.

In 2012, we attended the 19th International Oil&Gas Industry Exhibition & Conference (OSEA). We meet our customers and new friends in the exhibition. After candid talks with them, Dervos gets a lot of valuable suggestions and feedback. We will invest more in technology in butterfly valves and marine valves. Meanwhile, gate, globe, check and ball valves remain our major products. In the year to come, we are planning to participate in more overseas exhibitions. News will be updated. Thanks for your attention to Dervos.
