Claims

[Scope of utility model registration request]

The main spool is displaced within the valve hole formed in the valve body according to the pressure balance between the primary pressure from the pump and the pilot pressure controlled by the pilot valve to
In a pilot type relief valve configured to control the valve, the valve seat member for adjusting the pilot pressure is provided, and the valve seat member has a disc-shaped end face opposite to the valve seat forming end that contacts the valve body. A pilot type relief valve characterized in that a filter is provided, and a magnet is placed close to the filter.
