I'm not too familiar with them in general, but is there any that you can adjust to not close all the way, even though it's a normally closed unit? So instead of closing to zero, it closes to "20%"?
Adjustable normally closed electronic pinch valve?

Space is big.
The easiest method may be to install an adjustable bypass line so that some water will go around the valve when its closed. A gate or needle valve would allow you to fine tune the amount that still flows when the solenoid valve is closed.

I'm not sure a bypass would be acceptable in this situation. I'm trying to automatically purge gunk from the line that needs to be only partially open 99% of the time.
I'll be using my apex to control it, but I'm not sure if there's a non-metallic solution to this.. Or perhaps I need to be approaching it differently.

What is the purpose? The more information you provide, the more relevant the answers can be.

3/8" but I could do something around that diameter. Just a hose, probably vinyl.

A normally closed pinch valve, I assume from the pictures it's basically spring loaded so it doesn't use current during the closed position?
So I might be able to just jam something small in there alongside the hose to keep it from closing all the way?

A purge valve that needs to remain 5% open, but purged from time to time to allow gunk to pass.

Is the reason the gunk is being built up in the first place because of the valve? If it is I would think the best solution would be a peristaltic pump. That way you could control the flow that you want and there would be nowhere on the outlet for gunk to build as you wont need a valve for restriction. This is what most find to be useful in an application such as calcium reactor effluent where needle valves are prone to clogging. This is just a thought though as I am not sure what your actual application is for.
Let me rephrase....what equipment is the line running between and what fluid is being passed through it? (tank water, supplements, toppoff, etc)

he would have said already.... we just have to guess... this could be fun :clown:
there may even be a prize for the winner
I'll go first........nitrate reactor of sorts? :idea:
No fair, you can't call first, I already guessed......three times......and left it open ended..... Lets wait and see who wins.. :lolspin:
Whats this prize you speak of?
:beer:
You could use some silicone tubing and make a side plate the tubing would be up against and then mount THIS at the right distance away from the tubing so that when the solenoid is not energized it will put pressure against the tubing to keep it partially closed and then through your Apex you can energize it which will pull the slug back allowing full flow.
I don't think vinyl tubing will work in this application because it will start to have a memory from the pinch.
