The only mechanism of the valve that is adjustable is the stem packing. If adjustment is required the gland may be taken up on by first loosening the handle nut. Adjustment of the gland should be no more than one quarter turn at a time. Over tightening will produce high torque and a shortened seal life. MAINTENANCE A repair kit containing two seats, two body seals, one thrust washer and stem packing is available for rebuilding each size and style valve. Be sure to specify size, style, seat and seal materials when ordering. Optional components are also available (ball, stem, handle, etc.). Refer to illustration on last page for part identification and assembly. REBUILDING WARNING- Ball Valves Can Trap Fluids in Ball Cavity When Closed If the valve has been used to control hazardous media, it must be decontaminated before disassembly. It is recommended that the following steps are taken for safe removal and disassembly: -Relieve the line pressure. -Place the valve in half-open position and flush the line to remove any hazardous material from valve.

4 -All persons involved in the removal and disassembly of the valve should wear protective clothing such as face shield, gloves, apron, etc. CAUTION: Exercise caution that sealing and all surfaces are not damaged during disassembly, cleaning or reassembly. 1. Before removing valve from line, rotate ball into the open position. 2. Remove body bolts and disassemble from line, allowing sufficient pipe end clearance for center section removal. Remove body end seals from pipe ends. 3. Rotate ball into the closed position. Remove seats and ball. 4. If it is necessary to replace stem packing, remove handle nut, handle, stopper, stem nut, concave washer and ring. Lower stem into body cavity, Remove stem packing and thrust washer. 5. Clean and inspect all components to be sure they are free from foreign matter and pit marks, paying particular attention to areas that must maintain a seal (the surface against which the seats are installed, finished diameter on stem, ball, stem hole). These areas must be free from scratches and pitting. 6. Light marring from the action of the ball against the seats is normal and will not affect the operation of the valve. 7. Once all components have been cleaned inspected and replaced as necessary, the valve may be rebuilt with the appropriate factory repair kit. 8. Slide new thrust washer over stem and insert assembly through ball cavity and fully up into stem hole recess. 9. Assemble new stem packing, ring, concave washer and screw stem nut. Adjust stem packing to feel firm. DO NOT over-tighten. 10. Lightly lubricate ball and seats with a lubricant compatible with the media for which the service is intended. 11. Replace ball into cavity with stem flats in perpendicular position, making sure that portholes are in desired position for operation. Once ball is engaged with stem, rotate to in-line position to prevent ball from falling out during assembly. 12. Insert new seats into body and body end seals on pipe ends. 13. Replace center section back into line, allowing sufficient clearance to avoid pipe end sealing surface damage. 14. Assemble body bolts and nuts to valve. Put stopper, handle and screw handle nut onto stem. 15. Reinstall into service following the installation procedure. 16. If practical, check leak tightness before reinstalling valve inline.
