Regulating valve issues
Thread Content
Is there any specification regarding the orientation of the diaphragm chamber of a control valve during installation? It should still be installed based on the on-site conditions. Thank you
In general, they are installed vertically, but some may be quite tall (I’ve seen ones that are two to three meters high); in such cases, it’s necessary to check in advance whether the pipes in the vicinity might interfere with each other.
There are no strict rules; generally it goes upward, and adjustments can be made based on the actual conditions on site
Generally, the actuator is placed upward, but it is not necessarily required to be so; adjustments can be made according to the actual conditions on site. For example, the diaphragm chamber of the control valve on our cold boxes is installed horizontally.
Install it horizontally as much as possible to minimize the working friction within the valve components and extend its service life, unless space is limited
