[Reliability]
By making the springs and sliding portions less susceptible to fluid contact, malfunctions caused by clinging foreign matter are prevented.

[Abrasion resistance]
Adopting stainless steel material prevents flow path wear and damage.

[Corrosion resistance]
With stainless steel material used, it has corrosion resistance and can be used for water control.

[High pressure]
Adopts a metal sealing structure to prevent deformation of sealant, and is compatible with high pressure (7.0 MPa).
