Disc Holder Subassembly –<br />
1. Assemble new main seat disc and new pilot disc on to the seat<br />
retainer. Be sure the wording "seat side" on the main seat disc is<br />
facing down and the wording "seat side" on the pilot seat disc is<br />
facing up.<br />
2. Assemble the seat disc holder to the seat retainer assembly with the<br />
four (4) disc holder screws. Torque down to 115 to 130 inch/lbs.<br />
3. Install poppet through disc holder with wear button side facing<br />
down.<br />
4. Lubricate the inside bore of the disc holder and assemble the<br />
excess flow spring and spring retainer into the disc holder.<br />
5. Compress these items into the disc holder and secure by reinstalling<br />
the retaining ring.<br />
6. Set assembly aside.<br />
Stem/Actuator Assembly –<br />
1. Lubricate new inner stem bearing. Install in valve body.<br />
2. Install seal gland spring into valve body.<br />
3. Lubricate the threads of the seal gland. Carefully install the seal<br />
gland/stem subassembly into the valve body and through the inner<br />
stem bearing, engaging the stem seal gland gasket. Torque the seal<br />
gland down to 800 - 1000 in/lbs.<br />
4. Lubricate the cam driver and install on inside stem shaft. Align holes<br />
with that on stem and secure with new roll pin.<br />
5. Place new cam onto cam driver by aligning hex edges.<br />
6. Install retaining ring on end of shaft through slot next to the cam.<br />
7. Check to see the stem rotates smoothly by turning the cam.<br />
Bonnet Assembly –<br />
1. Install new seat o-ring and seat ring into valve body.<br />
2. Install new poppet seal o-ring into seat ring.<br />
3. Install wear button into poppet and secure with a new roll pin. Install<br />
poppet and Disc Holder Subassembly onto valve by carefully sliding<br />
poppet through poppet seal o-ring in seat ring.<br />
4. Lubricate the inside bore of the bonnet. Place the bonnet over the<br />
poppet and disc holder assembly. Orient screw holes in bonnet with<br />
those in body.<br />
5. Press down on the bonnet and install the four (4) bonnet screws<br />
with a 115 to 130 inch/lbs. torque.<br />
6. Assemble the strainer and strainer top to the valve. Secure with<br />
the strainer screws with a 50 to 60 in/lbs. torque.<br />
NOTE: The screen should be removed if the valve is to be used<br />
for both filling and withdrawal service or for filling alone.<br />
7. Assemble the new upper flange seal gasket and new lower flange<br />
seal gasket to the valve body. Install these seals just prior to valve<br />
installation.<br />
MANUAL/PNEUMATIC ACTUATOR REASSEMBLY<br />
Manual Actuator Assembly –<br />
1. Install lever on stem and align holes.<br />
2. Secure with new cotter pin.<br />
Pneumatic Actuator Installation –<br />
NOTE: Lubricant compound 11550-215, or the equivalent, should be<br />
applied in a light coating when specified. Torque tolerance is ±10 in/<br />
lbs. Refer to Diagram 2 during assembly of the pneumatic actuator.<br />
1. Remove the clevis and clevis locknut from the air chamber shaft.<br />
Remove the cotter pin and pivot pin from the clevis.<br />
2. Assemble the air chamber to the bracket using the air chamber nuts<br />
and lock washers. Center the air chamber shaft in the clearance<br />
hole of the bracket. Tighten air chamber nuts to 375 in/lbs.<br />
3. Reassemble the clevis locknut and clevis to the air chamber shaft.<br />
Adjust the clevis so that the center of the pivot pin hole is 2 3 /4" from<br />
the bracket with the pivot pin holes in the horizontal plane. Lock<br />
the clevis in place with the clevis locknut using 200 in/lbs. torque.<br />
4. Mount the above bracket assembly to the valve face with the<br />
bracket screws and lock washers. Be sure that the top of the<br />
bracket is even with the upper edge of the valve face and centered<br />
around the hex of the packing gland. Torque the bracket screws<br />
to 60 in/lbs.<br />
