Changing between Rod Extended when Energized and Rod Retracted when Energized

The procedure for changing between having the rod extended when energized and having the rod retracted when energized

Changing method 1

Changing method 1

1. Loosen the 2 hex socket head bolts with the appropriate tools and remove the plate and solenoid valve. When removing, instead of removing the plate and solenoid valve separately, remove them together with the hex socket head bolts still inserted.

Changing method 2

Changing method 2

2. There is a sub-plate gasket inside the sub-plate. Invert this sub-plate gasket by 180° and install it so that the letter "B" is visible. (A portion of the outer section of the sub-plate gasket protrudes. The letter "B" appears on one side of this protrusion.)

Changing method 3

Changing method 3

3. Install the solenoid valve and plate and then tighten the hex socket head bolts with a tool. Apply a tightening torque of 0.6 to 0.8 N·m.
After tightening, press the manual button on the solenoid valve to check for any air leaks and to confirm the operating conditions. Rod extended when energized and rod retracted when energized can be determined from the outside by looking through the small window on the sub-plate (ass shown in drawing).

Usage Precautions

  • *Do not rotate the cover. If the cover is rotated when installing a cylinder or screwing a fitting into the port, there is a risk the cover junction part will become damaged.
  • *The cover and cylinder tube are connected using the crimping method and so cannot be dismantled. Therefore, none of the internal parts of the cylinder other than the rod seal can be replaced.
  • *When replacing rod seals or when removing and mounting a retaining ring, use the appropriate tool (retaining ring pliers: tool for installing C-type retaining rings). Even if the proper tool is used, there is still a danger of injury or damage to nearby workers or equipment as the retaining ring may fly off from the tip of the pliers. As such take extra care when removing the retaining ring so as to prevent this. In addition, be certain that the retaining ring is placed firmly into the groove of the rod cover when mounting before supplying air to the cylinder.
  • *Use caution when handling a cylinder tube that is operating at high speed / high frequencies, as the surface becomes very hot and may cause burns.
  • *Do not use an air cylinder as an air-hydro cylinder. Use of turbine oil as the operating fluid for the air cylinder may result in leakage.
  • *Join the rod end parts to prevent the rod boot from twisting. If the rod boot has become twisted during cylinder installation, the rod boot may fail during operation.
  • *The above product is designed for use with a compressed air system only. Do not exceed the specified ranges for pressure or temperature, as this may cause damage, malfunctions, etc.
  • *When energizing valves for an extended period of time, heat generated by the coil will cause the temperature to rise, decreasing solenoid valve performance, decreasing the lifespan and adversely affecting nearby peripheral equipment.
  • *See the SMC catalog for information such as specifications, basic type dimensional drawings and diagrams other than those provided above.
