On June 24, 2016, Beijing Leiming Cyber Technology Co., Ltd. completed the delivery, installation, commissioning and training of the STM500SV COMBI valve maintenance machine at a certain military unit in Hainan.

The STM500SV COMBI valve maintenance machine is a product of German UNIGRIND company. It is a fixed-type maintenance equipment that can grind or polish the sealing surfaces and valve cores, gate plates and flange surfaces of gate valves, globe valves and safety valves. Before purchasing this equipment, the user had been using the traditional manual grinding method to repair the valve sealing surfaces. Not only could the grinding quality not be guaranteed, but the maintenance time was also long. The delivered equipment not only ensures the grinding quality, but also has a grinding efficiency three times that of manual grinding, significantly shortening the valve maintenance time. During the on-site training period, with the active cooperation of the users, the service engineers remained on-site throughout the day, overcoming difficulties such as high temperatures and tight schedules. They worked overtime to successfully complete the tasks and were highly praised by the users.
