1 TC-3000T/B/S & TC-3000TC &TC-4000 THREE PIECE BALL VALVE, 1000 WOG & 1500/2000 WOG INSTALLATION..OPERATION & MAINTENANCE INSTRUCTIONS TCI ball valves have been designed and engineered to provide you with long lasting trouble free service when used in accordance with the instructions and specifications mentioned herein. INSTALLATION 1. TCI three piece ball valves are bi-directional and may be installed for flow in either direction. During installation it is recommended that the valve ball be in the open position in order to prevent any possible damage. 2. After installation, cycle valve several times before putting into service. 3. Valves can’t be used on unstable gases. 4. Max. working pressure : TC-3000:1000 psi (69bar), TC-4000:1/2"~1" is 2000 psi(138 bar) 1 1/4"~2" is 1500 psi(103.5 bar) 5. Max. working temperature is 200..(392..). Caution for Brazing, Soldering, or Welding 1. If valve is to be brazed, soldered, or welded, the seats and body seals must be removed before installation in the following manner: (a) Rotate valve ball into open position. (b) Remove four body bolts. (c) Rotate valve ball back to closed position and remove seats and ball. (d) Remove body seals from pipe ends. (e) Place ball, seats, and body seals in a clean suitable container during installation. (f) Reassemble pipe ends to body. 2. When brazing, follow standard brazing procedures minimizing a direct flame on the valve body (center section). 3. When welding, it may be desirable to wrap a damp towel around the center section. 4. After brazing or welding allow the valve to cool. Reassemble the seats, seals, and ball with the valve. 5. Carefully tighten the body bolts diagonally across from each other before securing to the following recommended torque: Item No.: TC-3000 & TC-3000 TC VALVE SIZE RECOMMENDED BOLT TORQUE DN15~DN25 (1/2"~1") 16 –19 N-M (141.60~168.15 Lbf-in) DN32~DN50 (1-1/4"~2") 30 – 33 N-M (265.50~292.05 Lbf-in) DN65 (2-1/2") 75 – 80 N-M (663.75~708.00 Lbf-in) DN80~DN100 (3"~4") 140 – 165 N-M (1239.00~1460.25 Lbf-in) Page 1 of 6

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
