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

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.
