Above-mentioned response time is the figure on the non-lubricated at 0.5 MPa, and depends on the
pressure and quality of lubricant.
Pressure is converted as 1MPa=10.1972kgf/cm

≒
10.2kgf/cm

In case of use, consult separately of the continous energizing.
Note 1) Ambient temperature is the room temperature while component is stored or assembled system
is standing still and it differs from that of running media in operation
Note 2) When using low pressure (0.15MPa or less) lower than minimum working pressure, please use
following external pilot. The working pressure range is 0 to 0.7 MPa when the external pilot (op-
tion symbol:K) is selected. Set the pilot pressure between 0.2 and 0.7 MPa.
