Precautions

Design

  • *The exhaust port can clog due to a clogged or frozen silencer. Consider design safety to avoid malfunctions of the entire system. Also, under conditions conducive to freezing, use a freeze-reduction model (VCHNF Series).
  • *A silencer reduces compressed air exhaust noise from the pneumatic equipment. Noise other than that generated by the exhaust assembly (noise generated inside piping, due to equipment vibration, solenoid valve switching, etc.) cannot be reduced. For noise generated by sources other than the exhaust, locate the cause and take measures.
  • *Silencer inlet side pressure shows the solenoid valve supply pressure (P1). (See figure at right)
  • *The noise reduction may vary depending on factors such as the pneumatic circuit from which pressure is exhausted from the solenoid value, and the pressure itself.

Selection

*Select a silencer with a larger effective area (including the synthetic effective area) than the solenoid valve.

Mounting

  • *Tighten the silencer, using an appropriate wrench on the width across flats, within the range of the recommended tightening torque. Do not use a pipe wrench, which may damage the silencer.

Recommended tightening torque

  • Port size 3/4: torque 28 to 30 N·m
  • Port size 1: torque 36 to 38 N·m
  • Port size 1 1/4: torque 40 to 42 N·m
  • Port size 1 1/2: torque 48 to 50 N·m
  • *Do not apply a lateral load on the main body during or after mounting.
  • *If the silencer has loosened due to vibrations from the mounted equipment, mount the silencer after applying an anti-loosening agent to the thread.

Maintenance

  • *If the exhaust speed begins to slow from clogging and system functionality begins to degrade, replace with a new silencer or sound absorbing material.
  • *Also, be sure to confirm the actuator's operation status once per day.

How to Replace the Sound Absorbing Material

How to replace the sound absorbing material

When replacing the sound absorbing material, follow the instructions in the figure on the left.

  • Hex bolt: Tighten the bolt with a torque of 20 to 25 N·m after applying an anti-loosening agent.
  • The anti-loosening agent can be reused.

Other precautions

  • *See the manufacturer's catalog for information other than the above.
  • *Pictures are of representative models.
