*1: 0 to 60°C when diaphragm is NBR/EPDM.
*2: N.O. type not available for LVA10.
*3: If using with a vacuum, select products with a product number ending in -V. Cannot be used for vacuum retention. Moreover, using the B port side as the vacuum source may shorten the product lifespan.
*4: Applicable to LVC21 (N.O.) and LVC22 (double acting) types.
*5: Applicable to LVC20 (N.C.) -Z type.

Precautions

  • *Do not use metal fittings with a resin body (taper threads). This will cause damage to the valve body.
  • *Do not use if air leakage increases or the equipment does not operate correctly. After mounting, perform suitable function and leak tests to confirm that the mounting is correct.
  • *Mount and use the product only after reading and understanding the contents of the instruction manual. Be sure to keep the manual somewhere handy so that it can be referred to whenever needed.
  • *Be sure to read the individual product precautions before use.
  • *See the SMC catalog for product information other than the above.
