A spring bearing that urges the valve body in the valve closing direction by a quick-closing spring surrounds the bushing housed in the sleeve and the hydraulic cylinder, and when it slides on the bushing, the hydraulic piston and the hydraulic piston are arranged on the same axis. A hydraulically actuated main blocking valve characterized by:
