1 Pneumatic Actuators The TGA model is a double-action pneumatic actuator perfect for on/off control of the various types of butterfly valves. With an optional positioner, it can also be used for flow rate control. It mainly used for the medium to large-sized valves of size 350mm or more. The operation principle is that air pressure forces the piston inside the cylinder into a linear reciprocating motion, causing the trunnion coupled to the rod to drive the arm and rotate the output shaft.

3 TGA Operation principle As chambers A - A and B - B are connected through copper tubes as shown in the figure at left (single-acting cylinder is provided only with chambers A and B), feeding air into port S will generate a thrust to push the piston toward the left. The linear motion of the piston is converted to a clockwise rotary motion of the output shaft through the trunnion. Residual air in chamber B is exhausted through port O. Feeding air to port O causes the reverse of the action described above, rotating the output shaft counter-clockwise.
