1/4"NPT Solenoid Valve 4V210-08 12V/24V/110V/220V Single Coil Pilot-Operated Electric 2 Position 5 Way Connection Type

If you are used to electrical relays and micro switches where you have C NO NC then this is easy.The Port between vents is C. The bottom port is NO the Top is NC...The wiring displayed is for a heavily Earth grounded robotic system. As I installed this on a Truck I used just B+ and Neg. Their RED wire B+ their Blue wire Negative and I left the green off. This way the LED lights when engaged. I put a pipe plug into the NO port and only using the NC port. When releasing the Coil the Port does evacuate the air pressure.What I have done is used a Semi Brake can to operate a lever. Its internal spring returns the lever to nuetral.

I built my can crusher with this product. Worked out great for a Dual acting cylinder. You can press the blue thing on top to switch it manually or to reset the device. Make sure you order the correct voltage for your application.

Complete pos. Striaght threads that dont seal. Tried multiple fitting and teloned the crap out of it. Not worth the time lost trying to get it to seal. Which never happened.

For the price and with the accessories, I still can't really complain even though the valve has a constant small leak. I would still likely purchase again, although if I could buy a valve w/out the small leak for $1-$4 more, I would.

I paid about $16.00 or so not sure of what quality I would get. I was pleasantly suppressed. It works! Currently, I have it hooked up to 40psi and it leaks just a little between the valve body and the plastic pilot assembly. It came with some poly line fittings and mufflers. Not bad for the price.
