Improved OFF response
Specially constructed to improve the OFF response
when operated with a higher viscosity fluid such as oil.
Improved durability
Service life is extended by the special construction.

ClearanceClearance
By providing a bumper and clearance,
we reduced the collision sound of the
core when ON (when the valve is
open). Because of the clearance, when
using highly viscous fluids such as oil,
the armature does not get stuck and
the responsiveness when OFF (when
the valve is closed) is improved.
