Is it the instrumentation specialists who decide on the valve body structure and material selection for control valves?
This post was last edited by ROSEHOOD on 2010-6-22 08:42. Classified by specialty, control valves belong to actuators. The material of a control valve should be determined by the manufacturer based on the process medium specified in the order data sheet, but it must be approved by the instrumentation designer. The valve body structure of a control valve should be determined by the instrumentation designer, as the control characteristics are determined by the instrumentation design
Of course, it has to be the instrumentation specialty; this is determined based on the properties of the process medium and the operating conditions.
What does it mean to work with instruments? It sounds like LZ looks down on our industry.
Control valves are one of the important devices in the instrumentation field, and of course, they are determined by instrumentation. Other specialties cannot determine the structure of the control valve or the material of its body.
It is also possible to leave the choice entirely to the valve manufacturer, but it is necessary to inform them of the properties of the medium, the material of the pipes, and so on!
