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-5008) 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).
2. Rotate the Valve Rod so the hole in the Valve Poppet aligns with the Pipe Plug 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.
3. Slide the Upper Valve Block (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.
4. 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.
5. Use either Teflon tape or Pipe compound on the Pipe Plug (PF-AP-04-SS) threads
and screw into the Lower Valve Block.
