Actuators for high-temperature valves
Thread Content
How to determine the temperature range of the actuator for high-temperature valves? The temperature of the medium in the pipeline ranges from 300 to 600 degrees, while the ambient temperature is between 40 and 50 degrees. Choose a high-temperature valve; what temperature resistance is required for the actuator?
Can the actuator rely solely on ambient temperature? Can high temperatures be transmitted to the actuator through the valve stem?
Agree with what was said above; valve manufacturers will raise the valve supports to prevent heat transfer
So, what determines the design height of this bracket?
For valves that operate at high temperatures, radiators are designed on the upper valve cover or the service life is extended; this factor need not be considered when selecting the actuator
