Valve as one of the indispensable equipment in industrial production, from selection to use to maintenance may encounter many problems, here Xiaobian collected some common problems, see if it can help you?
1b What are the three main factors that should be considered in selecting the actuator?
(1) The output of the actuator should be greater than the load of the valve, and it should be matched reasonably.
(2) When checking the standard combination, it is necessary to consider whether the allowable pressure difference specified by the valve meets the process requirements. When the pressure difference is large, the unbalanced force on the valve core should be calculated.
(3) It is necessary to consider whether the response speed of the actuator meets the requirements of process operation, especially the electric actuator.
2b Compared with pneumatic actuator, what are the characteristics and output forms of electric actuator?
