ZECO metal seated ball valve is suitable for high temperature and high pressure special medium or medium with particles in the pipeline. Metal seated ball valve type selection based on different working conditions of the analysis and calculation, choose suitable working condition of hardness of the material hardness, to adopt advanced technology of spray welding on the surface of a sphere and valve seat sealing surface for special processing, grinding with hard sphere, and seat sealing surface makes the fit precision no leakage.
1. ZECO metal seated ball valve wear resistance, because the metal seated ball valve is alloy steel spray welding, valve body sealing ring is alloy steel butt welding, so as long as the medium hardness is lower than the hardness of the selected alloy steel, it will not produce too much wear;
2. The sealing performance of ZECO metal seated ball valve is good, because ZECO adopts automatic CNC grinding technology, and the machine grinding mating surface can achieve complete anastomosing, and the pressure test is completely in accordance with API 598 pressure requirements and standard time requirements, reaching 100% no leakage before passing the inspection;
3. ZECO metal seated ball valve switch torque light. Because the bottom of the sealing ring spring seal ring with the ball closely together, as long as the switch torque exceeds the pre-load of the spring when the switch will be very light, and in the configuration of electric actuator, can choose than other brands of metal seated ball valve a small number of electric actuator;
4. ZECO metal seated ball valves for high temperature has a long service life. Among ZECO's customers, there are petroleum, chemical, refining and other industries. In the history of ZECO company, the longest service life is 10 years.
If you are looking for reliable metal seated ball valve manufacturers, ZECO company can be your best choice.
