Does the electric valve open and close slowly?
Thread Content
Hello everyone, there is an electric valve here, and the process requirements specify that in addition to normal opening and closing operations, it should also be able to carry out commands for slow opening and slow closing. I’ve never seen a valve like this before. May I ask everyone, can electric valves achieve slow opening and closing?
Including the electronic control section, it is controlled using 4-20mA.
For linear actuators, even when the switch is activated, the movement speed in “mm/S” can be defined during configuration.
Hehe, no problem, it can be done. Electric valves are actually not very fast.
The switching speed of an electric valve depends on the gear ratio of the actuator; for example, in the case of an electric ball valve, the fastest time to rotate 90° is 1 second, while the usual time range is between 30 and 60 seconds.
An electric regulator with slow opening mode can be selected.............
I’d like to ask gently: does the poster mean solenoid valves and electric valves? ?
I'm talking about electric on-off valves. Thank you to everyone upstairs. Well, as required by the manufacturing process, this valve is equipped with a normal shutdown button, XHSC-*****A, as well as a slow shutdown button, XHSC-*****B. The presence of these two buttons together means that a valve needs to have two different speeds of operation, right? Can one actuator control one electric valve?
Once the speed ratio is set, it becomes a constant-speed motor, with its speed remaining unchanged, no matter which \"stop signal\" terminal is connected to it. Two motors can achieve a second speed level, but this feature is rarely used. Please confirm with the original poster whether the two valve control buttons are one for \"momentary shutdown\" (which requires holding down to close the valve) and the other for \"pulse shutdown\".
Electric valves are not fast to open and close anyway; if there is a time requirement, please mention it when placing the order regarding the desired opening and closing times
Switch-type electric valves do come in two types: those that open and close quickly, and those that do so slowly. This difference depends on the gear ratio; for the same valve, a different gearbox can result in different opening and closing times. Generally, the quick type takes around 3 to 5 seconds, while the slow type takes 45 to 60 seconds. The exact time depends on the application conditions (how it is used) Where is it used? ), but the motor’s characteristics still require a slower operation speed, with steady and uniform movement.
