Page 1 of 6 TC-0802A & TC-5000/5100 1/2”~8” 150#/300# FLANGED BALL VALVE 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 flanged 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. Install valve into pipeline and secure all flange bolts evenly. 3. After installation, cycle valve several times before putting into service. RECOMMENDED FLANGE BOLT TORQUES BOLT SIZE RECOMMENDED BOLT TORQUE M12 (1/2”) 100 ~105 N-M (88.50~929.25 Lbf-in) M16 (5/8”) 205 ~ 215 N-M (1814.25~1902.75 Lbf-in) M20 (3/4") 295 ~ 305 N-M (2610.75~2699.25 Lbf-in) M24 (7/8") 500 ~ 515 N-M (4425.00~4557.75 Lbf-in) M26 (1”) 780 ~ 800 N-M (6903.00~7080.00 Lbf-in) 4. Valves can’t be used on unstable gases. 5. Max. working pressure: TC-0802A/150#:275 psi (18.98 bar), TC-0802A/300#:720 psi (49.68 bar), 6. Max. working temperature is 200..(392..). 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 stopper indicates 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. 1
