The attachment is: the function of the Bench Set in control valves.
2. High reliability requirements for continuous production: Refining units typically operate for at least 8,000 hours per year, and the MTBF (Mean Time Between Failures) of valves must be over 100,000 hours. Safety interlock: It is part of the SIS (Safety Instrumented System) and meets SIL2/SIL3 certification requirements (for example, the emergency shut-off valve must operate within 2 seconds).
3. Precise control capability: Flow regulation accuracy: The control deviation of the distillation tower feed must be
