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 (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 or 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.
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.
5. Insert the Diaphragms (MPH-5010) into the Upper and Lower Valve Blocks with the
outside leading edge of the Diaphragms facing out. Push the Diaphragms all the way
down into the Valve Block bore.
