DESIGN CRITERIA – INSTRUMENTATION AND AUTOMATION

Failure of a level 2 valve will result in a total system trip, causing a shutdown of the entire unit, or other unavoidable losses in excess of $100K. However, the Level 2 valve’s process dynamics allow time for quick recovery from the failure, either by quickly fixing a fault or by taking manual control. The material and energy capacity of associated vessels, geographic location, and elevation/accessibility of such valves shall be considered. The difference in Level 1 and 2 valves are dependent on operations ability to respond to a single failure. Design Requirements: Level 2 valves and their associated measurement device (transmitter) shall reside on H1 networks/segments that are only used for control. The segment may have one Level 2 valve and associated transmitter when services are independent, or two Level 2 valves or a Level 2 and a Level 3 valve and associated transmitters when services are dependent. Dependent means that either of the two valves will shut down the same piece of equipment (example pass flows on a fired heater). 13.13.3. Level 3 Valves and Segments Failure of this valve will not result in any short-term risk of total unit shutdown or major operating losses. Level 3 valves can go to their fail position without requiring immediate operator action. Design Requirements: Level 3 valves can reside on cards or networks/segments with up to three other level 3 valves, or on a segment with a level 2 valve. Networks containing Level 3 control contain products from multiple (approved) vendors including measurement only devices. 13.13.4.
