Problems of electric control valve on air duct

Source: Manufacturer of electric control valve Release time: June 15, 2020 11:52

Today, I saw a post on the Internet. The sender said that the construction unit called him today and said that the electric control valve on the air duct Or solenoid valve. When the width of the air duct is greater than 1.2m, it needs two regulating valve actuators to meet the torque requirements. This is the first time he heard about it. Before, he always thought that a valve on the air duct of the same discipline was an actuator. In fact, this is not only the author thinks so, there should be many people have the same understanding, including Xiaobian. Fortunately, there are experts at the bottom of the post who have answered this question for me. The specific answers are as follows:
Sometimes, if there are too many actuators, it is very difficult to install one actuator. The actual wiring method is exactly the same. For example, Johnson's actuators can be connected in parallel, and the number of points will not be increased. That is to say, the number of DDC points will not be increased. It is enough to purchase more actuators.
Through the answer of the master above, I don't know if you understand it. I hope you have solved your doubts.
