A throttle check valve includes: a poppet valve body that has an orifice formed at one end and has a hole portion formed at a side portion; a plug that has a tubular shape to surround the poppet valve body, and functions as a valve seat to come into contact with the poppet valve body; and a spring that biases the poppet valve body and the plug functioning as the valve seat in directions to come into contact with each other. When the spool is at the second position, the plug forming the distal end portion of the spool and the plug arranged in the housing come into contact with each other. The plug is provided with a protruding portion that comes into contact with the poppet valve body.
