2 styles of Enderle K valve?

Is there 2 styles of Enderle K style barrel valve? Did the early versions not have a pump saver port?

 

Been a while since I have seen one but yes you are correct.

 

Yes, and it's great for cooling off the blower if you run the line to the hat distribution block instead of the tank.

 

So it does not have a pump saver port, but otherwise its the same?

 

Does any of you have a picture to show the difference. We are not running a pump saver and I am really curious as to how we plumb it.
We are using the k-style valve on alcohol but I wouldnt know if its a new style or old style, and dont have the pump saver plumbed. Any help is appreciated..........

 

Why couldn't his pump saver be installed inbetween the pump and barrel valve much like a HS or pump loop except the PSI setting would be higher?

 

OK, good news is I have the new style k-valve . Now my next question is when is it a good idea to step up to one and could some one take the time to explain why and then how to use it. Thanks guys I appreciate the patients for us new guys

 

I see no reason that you couldn't , i was going to suggest using a high speed T fitting and a pump saver poppet at the inlet of the K valve and running the line from the poppet back to the hat block.

 

It has to be set to 190/200 lbs.
