TAILONZ PNEUMATIC 1/4"NPT Solenoid Valve DC12V Single Coil Pilot-Operated Electric 2 Position 5 Way Connection Type 4V210-08 Outlet wire

This brand is nice to use. It doesn't extend and stay, unless it remains switched on. When turned off, it releases and the cylinder returns to starting state. I would call it push release. They are easy to use. Some cylinders may require buffer tank near by.

Works good

Bought this pneumatic for a scary halloween decoration and it works well. I have one from name brand sites and is say this works about just as good . Cheap too

I figured that 1/8" ports would be better for small cylinders, but it was a BIG LITTLE surprise when the 1/8" version was half the size of the 1/4 valves I'm used to. A 6-32 screw is too small to mount the 1/8" valve and the holes don't line up with 1/4" valves. I will send it back and use all 1/4" valves so they can be mounted in a stacked configuration. The 1/4" version will allow a common size screw to pass through the mounting holes....I didn't remember if it is 6-32 or 8-32 but one of them fits. Anything smaller is uncommon in sae sizes and for my use. The pictures seem to show the dimensions, but I assumed they were the same.....my mistake. The valves I bought in the past from this brand worked great, so I reordered the size I wanted.

Best customer service. Took care of my problem via email fast.

The quality Horrible. Why are the wires both exposed and melted?They do not work, (obviously),and frankly just look like someone broke it, panicked, grabbed the nearest soldering iron, and melted the wire on to the connection. I bought 2 of these and as you can see, they had the same problem.

I decided to try this valve out instead of buying the $160-$300 one that is sold by the manufacturer of the exhaust brake I put on my Dodge diesel pickup. It was easy to wire, came with all the fittings I needed to plumb it, had simple mounting holes, an led light on the solenoid to let you know when it's actuated, (nice feature when installed under the hood of a diesel truck) and has been working reliably for the last 3 months. Valve probably gets actuated no fewer than 150 times a day, automatically by my engines computer, and is switching 160psi air pressure with zero leakage.So I would highly recommend, and will use this brand in the future shall I ever have any more air or fluid switching needs.

Of the two I received, one LED was not soldered on completely, so the LED did not light up. Easy to fix however. Both had the wrong sized exhaust ports - 1/4" NPT instead of 1/8" NPT. Since I needed these and did not want to wait, I had 1/8" exhaust ports on hand to use. The 1/4" exhaust ports will go in the parts bin for another project.There are also 3 wire connects, and no indication of which to use. I tried the two that were near each other and that worked. Unsure of the purpose of the 3rd connection.
