Easy enough to to with a set of quick couplers with built in check valves. The check valves are opened when the couplers are connected.

Well this is not exactly a forum for domestic issues, but I suspect your query is concerning an indooe=r water tank of sorts ? n any case what you describe is a non-return check valve like already mentioned Depending what you want, size, material, fitting vonnection etc, you can pick these up on eBay by simply typing in Check Valve. An example here;- https://www.ebay.co.uk/itm/4mm-Plastic-CLEAR-Check...

Per ISO-4126, only the term Safety Valve is used regardless of application or design.

It is not a check valve, it is a dry coupling. A check valve prevents reverse flow. This is simply a coupling with a spring poppet valve that closes automatically when disconnected.

This is my first post. I need help with a type of valve that I need for draining a small tank. The principal is that the tank valve only allows flow when the valve is connected to a port where a small shaft pushes a simple sprung plug which allows flow. Please refer to images of the tank valve and the port that it sits in. The photos are of a simple carpet cleaner but I want to know the name of this valve for another application.

Thank you in advance.

Hi, did you had any luck finding the component?
I want to incorporate the same component in my design as well.
I'm starting to get the feeling that this is some sort of proprietary component, designed for a specific product and not commercially available, as nobody has knows the exact name of that thing, although they are more prevalent as one might think.
The closest thing that has a similar working principle is a quick release coupling (like for pneumatic equipment), but i just couldn't find the darn thing without the lock ring.

You need a name for this specific valve ?

I suggest:

1) "Poppet Check Valve"... or perhaps

2) "Roger"

Any name that will lead me to a valve with the same working principle:

• Fast connect/disconnect - no locking mechanism
• Always open - as long as the valve is engaged it will allow free flow (not pressure differential like in regular one-way check valves

I'll be sure to search for the names you suggested, thanks!

Thanks for the suggestion, but this thing has a camlock (any locking mechanism is absolutely out of the question) and the scale of products of the same nature is huge in comparison to what i require.

They are called quick release snap connectors like this

As you say you need a spring to make the upstream side close when you release the normally male component so you need some mechanism to hold the valve open. Hence the click when you press one side into another. Or the thing going into the valve has a certain weight able to be exerted like the example you show.

If you don't want the click effect then buy one of these simple units and take it apart to remove the click part of it.
