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
• Capacity
• Medium   temperature
• Pressure before  the  valve  and   after   the   valve
• Sound   level   required
• Connection  size
