Do emergency shut-off valves, pneumatic control valves, etc. fall under the equipment engineering field or the instrumentation and automation field?
Thread Content
Currently, our company is carrying out upgrades to the SIS system and environmental protection VOC systems as required by regulations, which necessarily involves the addition of things such as emergency shut-off valves (pneumatic) and pneumatic control valves. The question now is whether the daily testing, maintenance, and repair of these emergency shut-off valves, pneumatic control valves, etc., should be carried out by our Instrumentation and Automation team or by the Equipment team Now no one wants to take care of it; we’d like to hear everyone’s opinions. Usually, it’s the relevant specialty that is responsible for it. Another question: is it the electrical engineering department (in our company, the electrical engineering team has previously been responsible only for high-voltage systems) or the instrumentation and automation department that is in charge of the PLC modules in the control system?
Personally, I think what the original poster is talking about falls within the scope of responsibilities of the instruments····
Control valves should be maintained and managed by the instrumentation team, and the PLC of the control system should also be maintained and managed by the instrumentation team. Small PLCs specific to electrical equipment should be maintained and managed by the electrical department.
All pneumatic control valves fall under the instrumentation category.
Hydraulic and electric – we have instruments for all of them here; P;P;P;P
This division of responsibilities varies from company to company. I know that some companies use a separate management approach: all control valves fall under the responsibility of the instrumentation department, while for isolation valves, only the electrical components are under the instrumentation department’s oversight, with the rest being managed by the maintenance department. As for PLCs, some are under the electrical department’s management, while others are under the instrumentation department’s management. For reference only.
Generally speaking, the control part of the valve falls under instrumentation, while the mechanical body of the valve belongs to the equipment
Valves are generally considered instruments, and daily maintenance and repairs focus on these instruments; however, heavy tasks such as disassembling the valve body can be done by the equipment itself； Control systems definitely consist of instruments
