グバルブ。 A main spool and a pilot piston are placed inside the spool hole formed in the valve body and are arranged to face each other, and the opening degree of the control section of the main spool is controlled according to the pilot pressure acting on the pilot piston.
A holding valve that maintains a free flow state when the discharge pressure of the pump acts on the poppet formed in the main spool includes a seat portion that is pressed against the poppet, and a piston chamber that slidably accommodates the pilot piston. A holding valve in which a seat member formed with the above is installed inside the valve body.
