Venting high pressure gas or steam to atmosphere during a plant startup or shutdown generates unacceptable noise levels and subjects the vent valve to severe pressure drops. Use of a  D800 High Pressure Silencer  will greatly reduce the steam vent noise (or the gas vent noise) and create a back pressure on the vent valve to reduce the wear and tear on the valve.

The D800 Diffuser can be used as steam vent silencer to eliminate the vent noise or  a gas blowdown silencer to  eliminate the blowdown noise. It can also be used as a safety valve silencer.
