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
