Solenoid valve Proteus simulation

[dvalero484]

Hello.

I'm currently working on a project in Proteus 8 and I require a solenoid valve. Since there isn't a solenoid valve in Proteus, I'd like to know if there's any way to replace it in the simulation.

Thank you.

it depends how accurate you want it to be.

Basically it is just the valve´s ohmic resistance .. in series with it´s inductance.

But for sure this does not include the movement of the plunger, or coil heating ...

But indeed I ask myself how much sense it makes to "simulate a valve". What does one gain from it?

KlausST said my words. How much sense it makes to "simulate a valve". What does one gain from it. Solenoid is just a electromagnetic coil and there are many easier ways to simulate it. May be you can use a relay or simply a LED can indicate the working.

I thought of that, but I need to show the simulation and I was asked to display the valve.

It depends on what the purpose of your simulation is, electrical or functional? If functional, you can replace the solenoid with a bare LED, but if electrical, be aware that a solenoid is much more than just a solenoid, but rather a brutal source of EMI to neighboring components, as well as adding spikes on the bus. So, if you need to know if your simulation will work in real world, that is another point not covered by ordinary circuit simulations.

It all depends on application driven requirements. If all you are doing is watering tomatoes
then yes, an extended spice model is not necessary. But if you are trying to precisely supply
a fixed amount of gas or liquid for a chemical process, then the entire response of the valve
may be needed.

So yes, you and Klaus are correct for simple stuff, but for all applications in the galaxy maybe
good answer study the total application and act/design appropriately. As well especially given we are
in the IOT age of sensors and systems, where power is everything, and actuating versus holding
designs would be a good way of conserving power. And knowing what transient demands look like
in low power systems......so many design variants, not all simple !
