INSTALLATION
1. Before installing the valve in the pipeline, thoroughly clean the line of all dirt, welding chips, scale, oil or grease, and other foreign material.
2. $��� ��� ����� ������� ����������������������������through the valve body in the direction indicated by the arrow cast on the valve body.
3. A three-valve bypass must be used to permit removal of the control valve from the line without shutting down the system.
4. In case of a heat-insulated installation, insulate the valve body only, not the bonnet.

AIR PIPING
1. For an air-to-extend actuator (air-to-close action), connect the actuating air pressure line to the 1/4 NPT opening in the upper diaphragm case. For an air-to-retract actuator (air-to-open action) connect the actuating air pressure line to the 1/4 NPT to the lower diaphragm case.
2. Use 1/4 in (6.4 mm) O.D. tubing or equivalent for all air lines. If air line exceeds 25 ft (8 m) in length, 3/8 in (9.5 mm) tubing is preferred. Air lines must not leak. Air pressure not to exceed 35 psig (2.5 barg).

b. For type 177 trim (Fig. 4, page 11) unscrew retainer nut (24) using 3/4” socket wrench. Remove gland (23 ) and insert (25 ) . Replace insert (25), making sure that the tapered portion faces up. If replacement of the housing (26) is required, use a 5/8” socket wrench.
2E. NOLEEK™ Bellows Trim: (Refer to page 12)Hold bellows bonnet and push down on stem to expose plug retaining pin (21). Using a small punch, tap pin (21) out. To replace the new plug retaining pin (21), be sure plug and stem is aligned to expose hole (Fig. 5) and with needle nose pliers slide pin (21) into hole.

Lapping is the process of mating the valve plug to ������ ������������ �� �� ��������������� �������"����When valve seat leakage becomes excessive, lapping becomes necessary. The plug and seat ring seating surfaces should be free of large scratches or dents and the contact surface of the seats should be as narrow as possible.

2A. After removing the actuator, remove hex nuts (12), lift bonnet (8), and plug and stem (4 & 5) from valve body (1). A new body gasket (49) should be installed each time the valve is disassembled.
2B. Loosen packing spring load by removing the packing follower (10).
Remove the plug and stem assembly by pulling it out through the bottom of the bonnet (8) while rotating the stem (5). This will help prevent damage to the packing components.
2C. To remove the seat ring (2), fabricate a special wrench to engage the lugs on the ring. Clean the seat ring thoroughly and examine for signs of wear or damage.

Products Co. Grade 600 Crystolon) at several spots around the seating surface. Replace the plug and stem carefully in the bonnet.
3. Install the bonnet (8) into the body, without gasket and hand tighten. The bonnet will serve as a guide during the lapping operation.
4. Lap the valve by applying a slight pressure on the stem and rotate the stem in short oscillating strokes approximately 8 to 10 times or until you see an even and complete lap line. The plug should be intermittently lifted and turned 90º while lapping to keep the plug and seat ring concentric.
5. Clean the valve seat and plug (4) thoroughly when lapping is complete, removing all traces of lapping compound.
6. Reinsert plug and stem assembly through bottom of bonnet (8) by slowly rotating through packing. Being sure not to damage the packing rings.
REPLACING THE PACKINGRefer to assembly diagram (Fig. 1, page 6) and the standard and optional packing constructions illustration (page 13) to determine the packing that has been pre-installed in your valve.
1. Disassemble the valve as directed earlier. Remove the locknuts (27) and indicator disk (58), and turn the plug stem (5) out through the packing box. Remove the packing follower (10). Push out the old packing (14) by working from the underside of the bonnet (8).
2. [�����[�����.����!\]1��������$��� (see Fig. 1, page 6 & Fig. 6, page 13): Carefully insert each piece in exact order shown in illustration (Fig. 6, page 13). Turn the packing follower (10) until it shoulders on the bonnet (8). This will compress the packing spring (6) to enable constant stem sealing throughout packing life.
3. (���̂ ����������������$��� (Fig. 7, page 13): Carefully insert each piece in exact order shown in the illustration (Fig. 7, page 13). Hand tighten packing follower (10). Use a wrench to increase tightness by turning the follower an additional 60 degrees.
4. ]_1%�Q�[]�.® Packing (F ig . 8 , page 13 ) : Carefully insert each piece in exact order as shown (Fig. 8, page 13). Tighten the packing follower (10) until the Belleville springs are compressed.
����������������� �����#� ������"� �������� ������resistance. Back off the follower 1/8 to 1/4 turn. A gap of approximately 1/16 inch (1.5 mm) between the packing follower and the bonnet will make sure packing is seated properly.
5. For Optional NOLEEK™ Bellows Bonnet (Not available with 24000CVF carbon steel valves): NOLEEK Bellows Seal Packing (Fig. 5, Table 6, page 12): Insert each piece in the exact order shown in the illustration. Hand tighten the packing follower (10).
ACTUATOR AND BODY REASSEMBLY1. Insert a new body gasket (49) and install bonnet
assembly (8). For valve sizes NPS 1/2 - 1, tighten nuts (12) to torque of 7-13 ft/lbf (9.5-17.6 Nm); valve sizes NPS 1-1/2 - 2, tighten nuts (12) to torque of 16-31 ft/lbf (21.7-42.0 Nm).
2. Place the actuator yoke over the stem (5). While tilting actuator back, drop yoke drive nut (9) over stem (5). Run locknuts (27), and travel indicator (58), down as far as possible and counter tighten locknuts (27) to lock.See appropriate actuator instructions for reassembly and bench range adjustment.

[�]#%�.]_1%�Q�[]�.® PACKING NOTE:The ENVIRO-SEAL® PTFE packing system is suitable for 100 ppm environmental applications on services up to 750 psig (51.7 barg) and temperatures ranging from -50 to 4500F (-46 to 2320C).
For non-environmental applications, this packing system offers superior performance at the same temperature range up to the maximum valve working pressure.
Temperature limits apply to packing arrangements only. Complete valve assembly temperature limits may differ, refer to appropriate pressure/temperature ratings.
