What is the difference between this model with PEX Cold Expansion R10000-MF and the PEX Crimp R10000-PX? Is the insert barb bigger in the former than the latter to accommodate the stretched PEX during installation? Thanks.
Thank you for your question, David! The difference on these models is solely in the connection for the Inlets in regards to the type being used. Both will feature universal 1/2" connections, however the R1000-PX will have slightly tapered inlets for easier installation.

Pex inlet flow restriction...?
The inner dimension of the PEX inlets on these vale bodies are considerably smaller than any 1/2" cold expansion fitting I've seen (picture attached for reference).
After referencing different pictures of these cold expansion PEX valve bodies, some versions show larger inner diameters on the inlets, while some are smaller.
Wouldn't these inlets with a smaller ID restrict water flow?
Can you please provide the actual Flow/GPM of this specific valve body with these small inlets?
Are the inner diameters of the PEX inlets different between the WS and non-WS versions?
Thank you for your question! There is no difference in inlet diameter between MF and MFWS or any other with and without stops roughs. The difference in the inlets between PEX (MF, PX) and other valve types (UN, IP, etc.) will not produce a noticeable change in the flow rate as the waterways through the cartridge are more restrictive. The cartridge determines the flow rate, so the maximum flow rate will be determined by the series of trim that you use.
Here are the approximate flow rates for each series at 60 PSI:
14 series - 5.8 GPM
17 series - 5.9 GPM
17T series - 7.3 GPM

What size PEX pipe is needed for the R10000-PXWS inlet connections?
For the MULTICHOICE® UNIVERSAL ROUGH VALVE BODY - R10000-PXWS What size PEX pipe is needed for the inlet connections?
Thank you for your question.
The R10000-MF has 1/2" PEX cold expansion connections and 1/2" universal outlets with male threads. The R10000-PXWS has 1/2" PEX Crimp connections and 1/2" universal outlets with male threads.

What does the Pex Cold Expansion represent in this code and what would be the benefit of using this valve vs. the
Hi Rep, Thank you for your question!
The R10000-UNWS has 1/2" inlets for copper or iron pipe and would need an adapter to use PEX with with it. The R10000-MFWS is manufactured to be used with PEX.
