Hello,
Please my question may sound silly, but it will mean a lot to me if you answer. Here goes the question:
please can we use the same solenoid valve for both pneumatic and hydraulic system operation? I mean is the solenoid valve used in hydraulic system different from the one used in pneumatic system or solenoid valve is valve?
Thank you.

Hi Jose, I am going to try to respond to your question about which type of solenoid valve (two position or three position poppet valves are more efficient.

First of all, what, exactly, do you mean by efficient? There is some ambiguity here. One option is ‘efficient’ in terms of power consumption (measured in terms of Wattage), and the other is efficient in terms of the volume of media used (volume of compressed air of hydraulic oil?

The first case is dependent upon your coil and how long the coil is being electralised for? In the second case, this depends on the total volume within the valve body — the volume that the spool occupies, as well as how long the position is held for?

I hope that helps.

Hello Paul Heney,

I have gone through your blog, it gives very good information about solenoid valves. Here you explained about two types of solenoid valves i.e. two-way, two-position poppet valves and Three-way, two position poppet valves. Can you tell me which one is more efficient in oil and gas industry?

I look forward to hearing from you.
