By doing it this way, you eliminate issues with power supply voltage tolerances and overheating the coil. Don't be afraid (or surprised) that you have to tune this a bit but overall this is the correct way to drive a solenoid. Now put in the solenoid and verify that everything works as expected. This gives me about 150mA current pulse that decays out in about 5ms. To get about 150mA and for it to decay to a 90mA hold current, I paralleled a 100uF cap with the 57 ohm series R. Usually you want a series R at about 80% of the DCR so in my case that would be 57 ohms.

I had a solenoid that measured 9.6mH, at 10KHz and 1V. The Power through the coil sets the max current you want to run through the coil.

There is a difference between the initial current to drive the solenoid to its new position and the current to hold it there.

Suitable for fluids like water, oil, air.You do need a series R as well as a parallel C.

Not only can it provide a steady flow, but it also prevents the dry burning.

Pressure-regulating valve (steady flow valve) function similar to the water flow switch.

The installation direction can be arbitrary Angle.

It is not suitable for use with Gravity fed systems (Hint : Inside the value, at one side you will find the filter this is the input side of the value). It will work only if you connect it in the right direction. Note: While Connecting Valve in Flow pipeline, you need to mind the Input and Output direction of the valve.

As it is a normally closed assembly, it opens the flow of fluids as soon as it is powered ON and stops/blocks the flow when the supply voltage removed. The valve works with the solenoid coil which operates electronically with DC 12 volt supply.

LEG & HIP NS N 6530-0 NOMENCLATURE QTY ELECTRIC TURBINE MOTOR 01. When a 12V DC supply is applied to the two terminals, the valve opens and water can push through.

This liquid valve would make a great addition to your robotic gardening project.
