How to: QEV/piston valve (explicit)

Unread postAuthor: wyz2285 » Tue Nov 27, 2012 4:39 pm

I think I have mentioned everything people need to know about making a 1/2 QEV or a 3/4 piston valve...
The piston valve is the same as here, I learnt how to make it some years ago from it, the link was sent to me by this guy and that´s how I met spudfiles.

Any estimate on the cost of the parts? I would love to build a brass piston vavle, but costs have always kept me with PVC.

They cost me last than 20 euros for sure, probably less than 10 euro but I don't remember, made it almost 4 years ago.

Hmm... so on the for about 13 USD I can make a 3/4" metal piston valve or I can buy a premade 1/2" QEV for about 8 USD. Is there a benefit to using a homemade piston valve of this size versus http://www.ebay.com/itm/QE-02-Pneumatic-1-2-Inlet-Port-Air-Quick-Exhaust-Valve-/140878761173?pt=Pneumatic_Hydraulic_Valves_Parts&hash=item20cd074cd5?

Also, not sure how to shorten URLs when posting heh.

Homemade 3/4 has better flow and more stylish :wink:

Ah, one more question while I'm here - is there an account setting I can change so that I know when someone posts in a thread I've posted in? I've only seen your responses in this thread by coming back to it and I realize this will make it difficult to reply to anyone who responds to me in other threads...

Near the bottom of the page there's a button that says "Watch this topic for replies"


What would be ironic would be if you forgot to check for replies, and never saw this :P

Huh. It says I'm watching for replies... but I didn't see any notification when you posted. I'm I looking in the wrong places? Is there a place to see where replies are posted to watched topics?

Well there's the recent topics bar. It sends me an email every time someone replies in a topic I've posted in, I had to turn it off in settings, you you can probably turn it on. Or, try checking your junk mail folder.

Keep in mind that the QE-02 has a 3/8 inch port not the implied 1/2 QEV.

Didn't think about that. I'll keep it in mind.
