Solenoid valve

[alim777]

The item i received is not the same that was advertised in your website, i was supposed to get a solenoid valve that would switch open when 6-12v applied and stay close when there is no voltage. But it does the opposite when i apply voltage its closed and with no voltage it is open. Could i please get a refund or if you guys want to replace i would need to receive them as soon as possible.
Thank you!

Which valve did you order? The plastic or the brass?

[alim777]

It was the plastic solenoid valve

So are you guys going to resend the originals ones i ordered?

[adafruit_support_rick]

I'm still checking into our stock to find out what went wrong.

[adafruit_support_rick]

Our internal CS people are researching the problem. Let me know if you don't hear from them today.

[adafruit_support_rick]

All three valves you got are the same? Can you post a picture of how you have them connected?

[alim777]

I received the solenoid valves that you sent, in return for originally sending not functioning or incorrect parts, but i only got one plastic water solenoid valve 12v - 1/2, you did not send other two, could you please send them as soon as possible please, i need them by Tuesday for my graduation project, can you please send the 2 more of the Plastic Water Solenoid valve 12v-1/2" as soon as possible. Thank you.

Hello!
We are going to go ahead and send you another pair -- please post here your experiences working with the two options we sent you previously!

Thanks,
Adafruit Support, Matt

I only got one plastic solenoid valve 12v-1/2" it's working fine, but i need 2 more because i ordered 3 and you only send me one, could you please send me 2 more as soon as possible, i need them by Wednesday latest thank you.

They should be on their way already!

I recently bought these products from you.
2 x Liquid Flow Meter - Plastic 1/2" NPS Threaded[ID:828]
4 x Plastic Water Solenoid Valve - 12V - 1/2" Nominal[ID:997]

Before connecting them with Arduino and controlling through relays, I wanted to check how they work.

When I connected a power supply of 12V DC to the solenoid valve, nothing seems to happen.
I tried the same with all the 4 solenoid valves that I bought from you.

[adafruit_support_rick]

I believe the plastic valves have a minimum pressure requirement of 3 PSI, which must be applied before they will open.

[SFO_user]

Thank you for your response.
I also see that the water flow can only be one way. Is there anyway I can make it both ways?

[adafruit_support_rick]

No, it's strictly one-way, due to the pressure requirement.
The brass solenoid valve is two-way, and has no pressure requirement:
