For Oil (N.C. Type)
- *Can also be used for air or water. However, be aware that the maximum operating pressure differential and flow rate characteristics will be limited to the specifications range for the respective types of fluid being used.
- *When the fluid is oil ensure the kinematic viscosity is 50 mm2/s or less. The special construction of the armature adopted in the built-in full wave rectifier type gives an improvement in the OFF response by providing clearance on the adsorbed surface when it is switched ON.

Precautions
- *Be sure to read the individual product precautions in the SMC catalog before use.
- *When used at low flow rates with a pressure differential of less than 0.01 MPa, operations may become unstable. In such a case, contact the SMC support center.
- *See the SMC catalog for details on handling one-touch fittings and applicable tubing.
- *See the SMC catalog for information other than that detailed above.
