Joker valves

We are rebuilding a Wilcox and Crittenden Skipper 2 head. Page Belting in NH can supply the cup leather for $ 20.
The closest joker valve is a Groco, H-27-A with a Jabsco 44-101-1000 seal .Or...
We could add a gate swing check valve but...isnt there a better way?
We could fabricate a bronze plate to fit other joker valves...which would be best?
Or, could we cast one in silicone?
Weve made bronze castings but never rubber material.
Anyone have any experience or DIY references?
Thanks in advance for replies.
Happy trails to you
Mark and the manatee crew.

Re: Joker valves

In reference to the post above by GordMay:
On page 16 of the PDF, they describe the installation of the base plate as being the most difficult part of the re-assembly operation.
My solution for easy installation was to get 3>4 bolts and saw off the heads, then by threading the headless bolts into the base casting it provides an "assembly jig", you slide the base plate over the bolts down far enough to start the threads of the flat-head screws, then remove the headless bolts and replace with the remaining flat heads.
The spring is easily delt with in this manner, and you're not fumbling around trying to line-up all the holes, nor risking the misalignment of the base gasket.

Re: Joker valves

Bowdrie gets a high five from the manatee crew for this post.
Weve done this job a number of times and struggled to do this step.
Elegant solution. Weve used line up bolts before but sometimes you just dont see the easy way out.
These are fantastic heads and worth rebuilding.
Now all we need is a way to copy the original joker valve.
Happy flushing.
Mark and the manatee crew.

Re: Joker valves

You could 3D print a replacement joker valve using flexible fllament.

Locate a local hobbist 3D printer group. Most of 3D printer owners are up for a new challange to CAD and print..
