| Lubrication | Not required (if lubricating, use turbine oil class 1 ISO VG32 *2) | ||
| Temperature | *1 -5 to +50°C (60°C for air-operated type) | ||
| Mounting Orientation | *5 Unrestricted | ||
*1: No freezing.
*2: Do not lubricate if seal material is EPR.
*3: For low vacuums, keep the pilot pressure in the 0.125 to 0.275‑MPa range.
*4: The pressure differential between port 1 (A) and 2 (B) must not exceed the maximum operating pressure.
*5: However, if the external pilot is a solenoid type, SMC recommends mounting the pilot solenoid valve in an upward facing vertical or horizontal orientation.
