The main focus of electric actuators in water treatment is flow control. For example, the principle that conventional throttle valves use orifices or purely mechanical to reduce the area of the watershed is changed, and the relevant pilot valves are used to minimize the energy saving. Loss in the flow process; high control sensitivity, safety and reliability, easy debugging, and prolonged service life.
Generally speaking, the flow can be controlled by changing the flow cross-sectional area between the valve core and the valve seat of the electric valve of the electric actuator. But in fact, there are still many factors affecting, for example, while the adjustment area changes, the pressure difference between the front and rear of the valve also changes, which in turn will cause the flow rate to change. Therefore, the difficulty in the development direction of electric actuators in water treatment lies in how to effectively optimize the opening of electric actuators to control the flow, achieve the purpose of optimizing production and reducing costs, and how to better lock the amount of water flowing through the valve. Instead of aiming at the balance of resistance, it solves the problem of system dynamic imbalance.
