Can general manufacturers specify actuators for large-diameter pneumatic cut-off ball valves?
I’m not quite sure what you mean. As far as I understand, if you purchase a complete set from a valve manufacturer (valves + actuators), it’s usually possible to specify the brand of the actuator, such as Siemens or ABB
Is it the brand of the execution agency specified by the owner? If the valve manufacturer does not provide its own actuator, it is possible to specify a brand for the actuator to be used, but generally two or more brands from the same category should be chosen. It is also possible to specify the structural type of the actuator. Provided it’s safe and user-friendly!
The petrochemical industry doesn’t pay much attention to this; in the power industry, it’s quite normal to specify actuators.
Sure. Generally, for large-diameter ones, Rotok or other brands can be specified
Choose whatever you want – after all, you’re the owner. If you have money, spend it; that’s just being willful!
