Must an electric valve be equipped with a handwheel?
OP, it mainly depends on the operational requirements. If it is a critical component, a handwheel must be available to manually open/close it in emergency situations such as power outages. If it’s not a critical area, consider it on a case-by-case basis (such as considering funding issues).
Not necessarily; if there is a bypass line, it may not be needed. The main purpose is to allow for manual intervention in emergency situations (such as when automatic valves fail), thereby ensuring safety and maintaining normal process parameters.
It should be the same as a pneumatic valve. Let’s check the installation requirements
Generally, electric valves are equipped with manual operation.
It’s not necessarily the case; it mainly depends on the requirements of the manufacturing process. If there are auxiliary lines and front/rear sections, they’re not necessary; in the event of a fault, it can be taken apart for repair. If there is no auxiliary line and stopping is not possible, then a handwheel is the only option!
Electric actuators basically all come with a handwheel; it seems to be standard equipment
The handwheel is installed as a backup; it can be used when electrical control is not available, thus ensuring that the manufacturing process is not disrupted.
