Valve Block Reassembly:
NOTE: Removable thread lock compound will be required for reassembly. If either
one of the two valve rods unscrewed from the valve poppet (MPH-5005) during
disassembly, put one to two drops of removable thread lock compound on
threads and assemble.
1. Set the valve rod assembly into the lower valve block (MPH-5001).
NOTE: Rotate the valve rod assembly so the hole in the valve poppet aligns with
the pipe plug (PF-AP-04-SS) bore. Insert 7/32” hex wrench through the pipe plug
bore and into the hole in the valve poppet to hold valve rod assembly in place.
2. Slide the upper valve block (MPH-5002 or VPH-5001) into the lower valve block
(MPH-5001) and align properly. Screw the button head cap screw (F-BHCS-04C-16
SS) into the lower valve block.
3. Use one to two drops of removable thread lock compound in the female threads of
the valve pistons (MPH-2517). (See Figure 3) Shake off any excess thread lock
compound and screw onto either valve rod end. Repeat for process for the second
valve piston and remove hex wrench from valve block. Push in on the valve piston
from either end to position the valve assembly.
Figure 3:
Use only one or two drops of thread lock compound
in valve piston threads.
4. Use either Teflon tape or pipe compound on the pipe plug (PF-AP-04-SS) threads
and screw into the lower valve block.
