This push rod is configured to push open the check poppet of the operated check valve, and
In an operator check device in which one end of the pilot piston opposite to the push rod faces the pilot chamber, and these members are installed on the same axis, the pilot piston and check poppet provided with the push rod described above are installed in a sleeve. The mounting hole is formed near one end face of the valve body, and the mounting hole is formed on the same axis so that it becomes gradually smaller inward from the end face. This is an operating check device in which a pilot piston and an operating check valve are connected and installed inside the above-mentioned mounting hole.
