The adoption of API RP 553 is vital for minimizing environmental and personnel risks. By standardizing the design and testing of safety valves—often requiring compliance with fire-test standards like API 607 or API 6FA—refineries can significantly reduce the likelihood of catastrophic equipment failure. Regulatory bodies and insurance companies increasingly look to these standards to verify that a facility can achieve rapid, remote isolation of hazardous process streams during an emergency.
API 553 emphasizes design and operational practices to prevent water hammer, such as:

These are your everyday working valves. They modulate continuously to control pressure, temperature, or flow rate. API 553 highlights specific criteria for choosing sliding-stem globe styles or eccentric rotary styles based on the required rangeability—which determines how well a valve maintains precise control at the minimum and maximum edges of its flow parameters.
