CONTAINER VALVE - INSTALLATION INSTRUCTIONS

How To Create the MAV Closed System Container Package

Install & Secure MAV Container Valve into Container

Check Continer Neck
Use "Go Gauge" tool #001-619 and insert into continer neck. Go Gauge should fit completely down inside container neck as shown. If Go Gauge does not fit in neck, do not use continer.

Install Tamper Evident Ring
Place Tamper Evident Ring over Container Neck. Tamper Evident Ring is properly installed when it sits approximately 1/8" from being flush with Container Neck top opening.

Inspect Container Valve
Inspect Container Valve O-Ring and Retaining Ring for damage. O-Ring should not appear cracked or cut and Retaining Ring must be present and secured to container valve.

Prime Container Valve
Submerge Container Valve Body in a bucket of clean water prior to mounting. NOTE: If water cannot be used during installation contact your Micro Matic representative.

Mount Container Valve
Place Container Valve into Container Neck. Turn Container Valve clockwise until it drops. Now turn the Contianer Valve 1/2 turn clockwise until it drops again and locks into place.

Seat Container Valve
IMPORTANT: It is necessary to seat the Container Valve properly in the neck prior to step 7. While pressing down, rock the palm of your hand in a circular pattern. This will center the retaining ring evenly across area 2 on the neck.

Lock Container Valve to Container
Place Spindle Tool #740-076 over container valve as shown and secure in place by turning the spindle handle clockwise until no more clicks are heard Loosen the spindle handle until free, rotate the spindle tool 1/2 turn and retighten to insure no clicks are heard. Remove Spindle Tool.

Verify For Proper Installation
Verify that the contianer valve has been installed correctly by using the Verification Tool #741-043. Place the service tool on the container valve flange and rotate 1/6 of a turn clockwise. Using controlled force, move (rock) the Verification Tool side to side & back and forth. An incorrect seated valve will come loose during this operation. If neccessary, repeat steps 6-9.

Conduct Pressure Test
Optional: Pressurized Leak Testing by using the MAV Pressure Test Head #748-039 (EPDM), #748-042 (Viton). For additional information call (866) 755-4477.

Install Dust Cap
Secure around container neck, insert cap over container valve and turn clockwise to lock into place.

Secure Tamper Evidence
Install Red Tamper Evident Pin #102-423 by inserting into hole located on the top of the dust cap. Push red pin down until it is flush with the surface of the dust cap.
