Sun RDFALCN Relief Valve

It is a safety device used in various industrial and mechanical systems to protect equipment, pipelines, and containers from excessive pressure. Its primary function is to release excess pressure by allowing a controlled flow of fluid (usually gas or liquid) out of the system when the pressure exceeds a predetermined set point. This prevents catastrophic failures, explosions, or damage to the system and its components. This helps prevent the pressure from reaching dangerous levels that could cause damage or pose a safety risk.
