Recovery and Utilization of Helium for Cryogenic Valve Cryogenic Test
During the low temperature performance test of the valve, helium in the cylinder passes through the high pressure pipeline and enters the valve chamber to be tested. After the test, the cryogenic helium in the valve chamber is recovered into the cylinder through the original pressure pipeline, and the process of helium utilization and recovery is completed. Valve cryogenic test requires that the test valve be cooled in the refrigerant for a certain period of time, enough to condensate or solidify most of the impurity gases, so as to improve the purity of helium. Therefore, the purity of helium will not decrease significantly after cryogenic test, which meets the conditions of recovery and reuse.

What are the differences between forged and cast valves?
Casting is an integral casting of material in the die. Its stress distribution is uniform and there is no restriction on the direction of compression. The forging is made of the same direction of force, its internal stress has a directional, can only bear directional pressure.
Valve Buffer Structure for Reducing Vibration and Noise of Valve Opening and Closing
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.</div> <div>
World Industrial Valve Market
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.
