Where to buy a 1inch butterfly valve

ben brinnand · May 23, 2019

Hi All.
I'm trying to source a 1" butterfly valve? I can only find ball valves.
(if your interested why)

Its to make a throw line launcher, I'm a tree surgeon and we use a small line and a throw bag to pull up our main climbing rope into a tree.
For bigger trees it takes time to hit the right branch, this thing can launch the sack 30m accurately

To me a butterfly valve isn't the one pictured. That is just a 1/4 turn lever valve and you would get them from most merchants.

Hi Ben

From what I've seen on YouTube, the valve is basically the 'trigger', is that correct?

Hi all
this one shown here is a 1.5 butterfly valve but the 1" (attached to the launcher on the table) is better because the release torque is lower.

Hi yes. But the air out of a ball valve escapes on one side pushing past the sack and not launching it properly.

Hmm. Okay. Get that. So what that means is that speed of operation is vital and this is why the guy on the video uses a smaller valve with lower operating torque hence increased speed and air distribution.

I see the issue. To me, the easiest way around this problem is a 12v solenoid valve. An electrically operated valve that opens in approx 0.2 secs (far faster than you'll ever be able to turn something). Using one would also mean much better accuracy as both hands can be used to aim as in a rifle.

The better quality valve you buy, the more pressure it will stand and the faster it will operate. Seeing as time is money in your business, I'd test it out with a cheaper version then upgrade to something more robust, more reliable. The actual 'trigger' then becomes a simple push to make button.
