So here is basically prototype 1.5. Chemline only had 3 1" valves in stock and nothing else, and @getherdone contacted me about alternatives to waiting until the end of January, so we came up with this solution. He opted to have the 2 1" Chemline valves and have the 1/2" valve be a GF 523 model. He was okay not having all the valves match, and Chemline was able to get me 2 of the 1" valves quickly, so we went this route.
The manifold is slightly different. I’m using street elbows this time so the valve socket can glue directly onto the elbow, eliminating some of the height that the overall system has. I think this will be a good improvement. Also, @tireshark, provided his own check valves because I hadn’t got that part sorted out yet, so for this one, it has the 3/4" and 1/2" hastelloy check valves. They are very nice. After going back and forth with @tireshark a bit, we thought that 1" inlet barbs would be too large probably, so the decision was made that 3/4" inlet barbs for SH and water would be best, and those mate perfectly to the 3/4" check valves. Those will pass through a bushing into the 1" metering valves.
I think this is a great step forward, and I should be able to assemble it tomorrow. I need to cut the sch 80 pipe that goes between a few pieces still and then glue everything up. There is still a question of if it’d be better to use threaded ends on the metering valves, but I’m hesitant. A glued joint is much stronger and reduces the likelihood of leaks significantly. And since they are true unions, the valve itself can still be removed if needed. But the locking nut will remain locked on the manifold and upper parts. I do think that a glued socket is going to remain the best option though.
Let me know what you guys think or if you have suggestions at all.
