PULSCO’s Blowdown Vent Silencers and Line Silencers provide the solution to high intensity, broadband noise associated with pressure relief systems and gas/steam line turbulence.  PULSCO Vent and Line Silencers are designed and engineered as a system, specifically matched to a Fisher Control valve system to reduce the overall cost for the valve and silencer package.  An integrated system optimizes valve performance, reduces valve generated noise, reduces valve size and noise trim requirements and reduces costs of piping and valve systems.  If a valve currently exists in the system, then PULSCO will match the silencer to the valve's operating parameters.  PULSCO’s product names were once focused on a component of the systems or a component of the benefits they produce.  Recently, we decided to clearly identify our products for the problems they address.  Below is a link to our new product names, the names they are replacing and what the product controls.  Common Product Names Chart
Vent
PULSCO’s Vent Silencers provide the solution to high intensity, broadband noise associated with pressure relief systems.  Vent Silencers are used to suppress noise generated by high velocity gas streams such as steam vents, safety relief valve outlets, system blow downs and purge outlets, and boiler startup and shut down systems.  Read more
PULSCO Vent Silencer large or small; we can configure one to solve your noise problems.
Line
PULSCO’s Line Silencers are used to control the noise produced by centrifugal compressors, ow control valves or pressure reducing valves in piping systems.  The line silencer is close-coupled with the piping system control or pressure reducing valve and reduces the aerodynamic noise resulting from gas or vapor turbulence.   Read more
