I'm hoping to control the flow of chemical by shutting a solenoid valve periodically over short intervals, similar to this video: https://youtu.be/O49mqn33vBI?t=6
Does anyone know if conventional solenoids can be controlled by PWM to produce, say, 500 cycles per minute? Is banging a 'conventional' solenoid that rapidly a good idea usually? By conventional solenoids, I mean those found in coffee machines and others commonly available:
If not, how are PWM solenoids constructed differently?
Any thought appreciated.
