Yongjia Nanguang Valve Co., Ltd. is a professional company manufacturing low & middle pressure valves. On the basis of more complete product structure than similar products at home and abroad, combining China's actual conditions and working conditions, taking advanced technology from abroad, our company realizes the optimization of valve technology parameters. Through more than two years of continuous improvement, our company has adopted Germany advanced product standards, and has successfully developed a series of products like seal valves, globe valves, check valves, traps, and strainers. The main features of our products are listed as follows:1, Our valve features good appearance and smooth channel line that reduce flow resistance coefficient. So they are energy-saving products. 2, Our valves use materials of graphite and stainless steel, with reliable sealing, which do not have to change packing after the long-term use. Valve leakage has obvious damage: high temperature, highly toxic damage, inflammable damage, explosive damage, and radioactive leakage media which not only pollutes the environment, but also causes significant personal and financial losses. The sealed structure of our products can effectively solve the problem of leakage, so we enjoy the reputation of green products from abroad. 3, The designing and manufacturing standards of our valves are in accordance with advanced German standards strictly, and the inspection test is in accordance with DIN3230 standard strictly. 4, Our valve features small torque, which can reduce labor intensity, and can take any form of device drivers, convenient for remote control. After the introduction of valve features, our products are favored by the majority of our customers. With the principle of Domestic products replace imported ones, we have installed the imported equipment in hot oil, power plant, vacuum, and petrochemical and thermal system.
