Hi Ed

Quite a few members at my club use them, I've drawn them and made a few sets and passed them on, so far they seem to have worked, if you PM me with your email adress I'll pass the drawing on.

Hi Guys

Search in Wikipedia for steam drain cocks for a drawing and then you can also follow various links

Edited By Essm on 16/01/2020 21:55:03

Sorry - search should be for Automatic cylinder cocks and not as previously shown

Edited By Essm on 16/01/2020 22:03:19

Please disregard this post altogether  - I am searching for correct link

Looking at the index to Model Engineer at **LINK**

There are two references to 'Steam Operated Draincocks' but that doesn't mean there are not others under references to particular model designs.

In 2015 there was a short article on Steam Operated Drain Cocks in David Carpenter's Model Engineers Website. I like the design and eventually plan to make a set as described by Peter Squire.

Usual "for personal use only" applies to downloads, so check the website:-

Doubt there's a problem with me showing the article's heading:-

(You could PM me if interested)

My preference is for manually operated drain cocks.

If the engine starts to prime , you can open a manual drain to release pressure and prevent damage to the cylinder, piston, etc.

Greetings Paul, I have been using steam operated drain cocks for some time, and they are completely controllable, just like taper cocks, just close the steam valve and they open to clear condensate, but with the added bonus that they will open automatically if you get a hydraulic lock.
