As the use of regulating valve, the inevitable result of the fluid decompression, speed changes and vibration, noise generation is difficult to avoid, the problem is to control the size of the noise. In process installations, noise-producing equipment such as motors, pumps, compressors, boilers, regulating valves, etc., and regulating valves account for a significant portion of the noise. The types of control valve noise are mechanical noise, hydrodynamic noise and aerodynamic noise.
