Chattering vs. Simmering in Safety Valves
Reliable safety valve operation is extremely important for the safe operation of boilers and steam systems.
Chattering - A condition in which the safety valve disc rapidly opens and closes, causing vibration, noise, and potential damage to the seat and disc.
Simmering - A condition in which the safety valve
continuously leaks steam at a low rate, usually due to improper sealing, worn or damaged seat/disc, or foreign particles.
