As the exclusive UK partner of Stopson Italiana, Wisebros offers engineered in-line pressurized silencers designed to reduce noise generated by control valves and compressors in pressurized piping systems. These silencers represent the highest standards in acoustic engineering, combining advanced materials with precision manufacturing to ensure performance, safety, and long-term durability.
Advanced Noise Control for Pressurized Systems
In-line silencers are directly integrated into the pipeline to absorb noise at its source—particularly downstream of control valves or compressors. These systems require:
- In-depth acoustic and fluid dynamics engineering
- Accurate material selection
- Precision manufacturing standards
- Expertise in pressure handling and velocity control
Stopson Italiana’s in-line silencers are the result of extensive testing and field-proven performance. They are engineered with special sound-absorbing materials capable of maintaining high acoustic efficiency in pressurized environments, without being directly exposed to the gas flow—preserving material integrity and acoustic absorption over time.
Design and Installation Principles
Each in-line silencer is flanged both upstream and downstream for direct pipe integration. Due to flow and velocity dynamics, the silencer typically requires a pipe diameter increase to accommodate speed control and ensure pressure integrity.
Proper acoustic and fluid-dynamic sizing is essential. The actual fluid density and operating pressure are calculated to prevent internal material displacement and performance degradation.
Best practice: When the source of noise is a control valve, the silencer should be positioned immediately after the valve to capture and attenuate noise at its peak generation point.
