ブ。[Claims for Utility Model Registration] A valve body 1, a valve shaft 2 rotatably disposed within the valve body 1, and a flow path within the valve body by rotating the valve shaft 2. In a valve that has an arbitrary valve body 3 that opens and closes, and has means for sealing the gap between the valve shaft 2 and the rotating sliding surface 9 around it; magnet 7
The magnetic fluid 8 is formed by the action of the magnet 7.
is concentrated in the gap between the valve shaft 2 and the rotating sliding surface 9,
It is constituted as a magnetic seal unit 5 designed to seal the rotation of the valve shaft 2, and
This magnetic seal unit 5 is disposed around the portion 4 facing the outside of the valve body 1, and the magnetic seal unit 5 itself is attached to the valve body so that it can be attached and detached from the valve body 1 integrally with the valve shaft 2. A valve characterized in that it is attached to the body via attachment means 14.
