Tungsten Carbide Coated Valve Ball
The valve is controlled by the combination of valve body and disc. When the valve is closed, the pressure difference at the inlet and outlet ends is different. At the moment when the valve is opened, the existence of pressure difference will cause a huge instantaneous impact on the valve components and pipelines when the medium passes through the valve, resulting in valve vibration and noise. Vibration has an impact on the sealing performance, service life and other testing equipment of valves and pipelines connected to them. Under some specific high-pressure conditions, especially the valves used in high-pressure pipeline system, their vibration is particularly severe, which can not meet the requirements of smooth operation, small vibration amplitude and low noise.
World demand for industrial valves is projected to climb 4.3 percent annually through 2019 to $98.5 billion. Market advances will be stimulated by growth in chemicals and other process manufacturing output, electric power generation, and construction activity in a generally healthy economic environment.
Metal Goods Manufacturing (MGM) announced its certification to the Pressure Equipment Directive 2014/68/EU, covering its line of excess flow check valves and back pressure check valves. MGM can now stamp its check valves with the CE Mark.
