Safety Valve Silencer
Noise in some safety and control valves generates levels above 150 dBA / dBC, a situation that is a concern for the technical operations and maintenance of plant. Our silencers reduce the noise generated during atmospheric expansions of steam or gas (vents) during the activation of valves, blow downs and ejectors. Noise exposure increasingly limits system and profitability productivity.
Every industry makes use of Safety Valves to protect systems against over pressure when these safety valves are opened to vent steam, gas or vapour it is often accompanied by excessive noise levels. Noise level as high as 150 to 160 dB (A) are not audible / unacceptable. It will affect the hearing level of employees and complaints may also be received from surrounding residential areas or factories.
The following process values are required to make the appropriate selection.
- Medium temperature
- Pressure before the valve and after the valve
- Sound level required
- Connection size
