Special Trim 3R Spirax Sarco

Possible Applications

This trim is engineered for high-pressure drop control valves installed in steam distribution headers and power plant bypass systems where aerodynamic noise generation poses a significant risk to piping integrity. It is specifically deployed in petrochemical refining units and large-scale industrial boiler houses to mitigate the acoustic energy produced during high-velocity gas or steam expansion. By utilizing a multi-stage pressure reduction path, the trim effectively prevents the onset of sonic velocity and cavitation-induced vibration in critical process control loops. This makes it an essential component for maintaining operational safety and extending the service life of control valves located in noise-sensitive environments or near sensitive instrumentation.
