4.2 Disassembly and Assembly of Actuator
GENERAL INFORMATION
The Honeywell pneumatic cylinder actuator moves the piston in the cylinder pipe, which is transformed
into rotation and moves the valve. This procedure is to adjust the valve position to the required position
by responding to control signals using air pressure.
The components of a spring return type actuator are pressed down by a spring. Take
general safety measures and disassemble correctly. Otherwise, injuries and damages
may result.
4.2.1 Disassembly (See Fig 4.1)
① Remove actuator from the valve.
② Release the air pressure from inside the actuator and disconnect the air piping.
③ Replace 2 tension bolts and remove the others.
④ Slowly remove the remaining 2 bolts while keeping the actuator spring without load.
⑤ Remove the cylinder cover.
⑥ Remove the pipe, and then remove the piston from the spindle.
⑦ Remove the spindle from the arm while taking care not to damage the surface of the spindle,
and then pull out the arm from the housing.
⑧ Check the O-ring and wearing, and replace them if necessary.
4.2.2 Assembly (See Fig 4.1)
Assemble in the reverse sequence of the disassembly.
