Noise created from unexpected release of gas from a safety valve to atmosphere could often exceed 150 dB (A) at 1 meter. PRAcoustics safety valve silencer will reduce such noise to environmentally acceptable levels (such as 85dB (A) as specified by Indian Pollution Control boards). Design of our single-stage diffuser assembly is in compliance with ASME section 8, division 1 standards. Length, diameter and other parameters of the silencer muffler are optimized based on the flow conditions of the medium and the noise performance requirements. Typical applications include boiler drum safety valves and super heater safety valves.
