2 Item No.: TC-4000 VALVE SIZE RECOMMENDED BOLT TORQUE DN15 (1/2") 16 –19 N-M (141.60~168.15 Lbf-in) DN20~DN25 (3/4"~1") 30 – 33 N-M (265.50~292.05 Lbf-in) DN32~DN40 (1-1/4"~1-1/2") 75 – 80 N-M (663.75~708.00 Lbf-in) DN50 (2") 140 – 165 N-M (1239.00~1460.25 Lbf-in) 6. After installation, cycle valve several times before putting into service. OPERATION 1. A quarter turn of the handle clockwise closes the valve and a quarter turn counterclockwise fully opens the valve. Visual indication of the ball position is determined by the handle position: when the handle is in line with the piping the valve is open, cross line the valve is closed. Also, the stem flats indicate the direction of the ball port. 2. Soft seated ball valves perform best with the ball either fully open or fully closed in accordance with TCI Valve published pressure/temperature chart. Consult the factory regarding characteristics of the media or pressure drop for applications other than fully open or closed. 3. Any media that might solidify, crystallize or polymerize should not be allowed to stand in the ball valve cavities. In the event that this should happen, DO NOT forces the valve in either direction; disassemble and clean before resuming service. 4. Force required to break-away (i.e., force which must be exerted to begin motion of ball) will vary depending on the media, pressure and length of time between cycles. The following data will act as a guide regarding break-away torques: Item No.: TC-3000 VALVE SIZE MAXIMUM BREAK-AWAY TORQUE DN15 (1/2”) 4.5 N-M (39.83 Lbf-in) DN20 (3/4”) 8.5 N-M (75.23 Lbf-in) DN25 (1”) 11.0 N-M (97.35 Lbf-in) DN32 (1-1/4”) 15.0 N-M (132.75 Lbf-in) DN40 (1-1/2”) 24.0 N-M (212.40 Lbf-in) DN50 (2”) 32.0 N-M (283.20 Lbf-in) DN65 (2-1/2”) 45.0 N-M (398.25 Lbf-in) DN80 (3”) 65.0 N-M (575.25 Lbf-in) DN100 (4”) 100.0 N-M (885.00 Lbf-in) Page 2 of 6

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.
