Design restrictions for automated on/off safety loops.

Refineries are hazardous environments. A single valve failure can lead to:

However, industry discussions often conflate API 553 with the broader family of valve standards, including:

API RP 553 provides criteria for choosing piston (double-acting or spring-return) and diaphragm actuators. Actuator sizing must account for peak breakaway torque or seating thrust under maximum differential pressures, ensuring the valve functions perfectly during process upsets.
