04. PRODUCT OVERVIEW WEEPLESS MVR INTRODUCTION (76624) The material regulator valve (MVR) is an air operated The tapered area on the needle and the fluid port valve that slides. It has a tapered needle and specially configuration let fluid flow through the MVR proportional designed fluid ports to permit precise regulation to the air pressure control signal.
05. SERVICING WEEPLESS MVR SERVICING PRELIMINARY PROCEDURES Before the removal of the MVR for servicing or COMMON MVR ISSUES repair, do the following: 1. Improperly filtered fluids cause the most common operation issues with the (MVR). 1. Flush the MVR with the system purge. Particulates and residue in the MVR can plug the fluid 2.

06. MAINTENANCE 4. Remove the M4 x 20 mm screw (f) and upper diaphragm support (g). 5. Remove the air diaphragms (h). 6. Remove the bottom diaphragm support (i). NOTICE Set the upper and lower diaphragm supports on a clean, lint-free surface. 7.
Page 19
06. MAINTENANCE 9. Flip the assembly and re-tighten the vise. 10. Remove fittings (l & m). NOTICE Set the fittings on a clean, lint-free surface. 11. Remove the four screws (n), fluid housing end cap (o), and the fluid housing (p) assembly from the lower housing (e).
Page 20
06. MAINTENANCE NOTICE Only remove the rolled steel pin if it gets bent during the disassembly procedure and needs to be replaced. Disregard this step if the pin is in good condition. 12. If damaged or bent, remove the rolled steel pin (q) from the fluid housing with a vice or pliers.

06. MAINTENANCE 18. Remove the seal retainer (u) from the head of the bushing guide (v). 19. From the pulled guide bushing (v) assemblies, remove the following: • Small backup rings (w) • Small O-rings (x) • Large high-pressure backup rings (y) •...
06. MAINTENANCE INSPECTION Use an applicable solvent and clean the remaining material from all MVR parts. Examine the following parts for wear and damage: 1. The needle (k) must measure the same diameter at the ends and center. Replace the needle and bushing as a set if the needle does not measure the same at the three locations or if there are scores, scratches, or damage to the needle.
Page 23
06. MAINTENANCE 5. Replace fittings (L and m) if they leak, are worn, damaged, or have thread damage. 6. Examine the edges of the upper (g) and lower (i) diaphragm supports for raised and sharp nicks that can damage the diaphragms. NOTICE Minor nicks can be filed, but if they cannot be smoothed, the support must be replaced.
06. MAINTENANCE ASSEMBLY Needle Preassembly 1. Assemble the upper diaphragm support washer (g) onto the screw (f). NOTICE The radius side and edges (ee) of the upper diaphragm support washer points away from the bottom of the screw when correctly assembled. NOTICE While not required, it is recommended that the...

06. MAINTENANCE 3. Put the lower diaphragm support washer (i) on top of the diaphragms. NOTICE The radius side and edges (ee) of the lower diaphragm support washer points at the diaphragms when correctly assembled. 4. Apply a small quantity of blue Loctite 243 (not included) onto the screw threads.
Page 26
06. MAINTENANCE 6. Tighten the screw (f) and diaphragm assembly onto the needle. NOTICE When the needle is tightened, it can be held in place with a padded vise or pliers, or with a second Allen wrench in the hex socket at the bottom of the needle. CAUTION The needle has a precision machined surface.

06. MAINTENANCE Guide Bushing Assembly 1. Press the O-ring loaded U-cup seal (aa) into the foot of the guide bushing (v) until fully seated. NOTICE The foot of the guide bushing is identified by the lack of threaded holes that exist only on the head of the guide bushing.
Page 28
06. MAINTENANCE 6. Put the seal retainer (u) onto the bushing guide head. Make sure the alignment pin on the seal retainer is set into one of the two non-threaded holes. 7. Repeat steps 1 through 6 to assemble the second guide bushing assembly.
Page 29
06. MAINTENANCE CAUTION Carefully move the fluid housing onto a clean, lint-free surface during reassembly. 1. If required, install the new rolled steel pin (q) into the pin hole (gg) in the bottom of the fluid housing. 2. Apply Teflon tape (not included) to the fitting's threads.
Page 30
06. MAINTENANCE 6. Align the weep hole (hh) in the fluid housing end cap (o) to the same side as the flat mounting face on the lower housing (e) and lay it on top of the fluid housing. 7. Apply a small quantity of blue Loctite 243 (not included) onto the screw threads (n).

06. MAINTENANCE 11. Apply a small quantity of petroleum jelly (not included) onto the outside diameter of the needle. 12. Align the needle and diaphragm assembly into the needle bushing in the fluid housing assembly. Apply petroleum 13. Carefully slide the needle into the bushing until the jelly here lower diaphragm support rests on the top of the spring.
Page 32
06. MAINTENANCE 16. Tighten the screws in a crisscross sequence pattern in a minimum of two steps. NOTICE While the bolts are turned, the internal spring load will keep force against the MVR housing halves. It will be necessary to keep equal tension on the housing bolts to avoid damage to the MVR's internal components.
