Abstract: A damping valve includes a main valve opening and closing a main passage, and a pilot passage reducing a pressure of the upstream of the main passage by a throttle to guide as a back-pressure biasing the main valve to the closing direction. A pressure control valve being disposed on the downstream of the throttle and including a seating portion controlling the back-pressure, and a switching valve including a circular depressed portion opening and closing the pilot passage are integrated and controlled by a single solenoid. The damping valve includes fail passages being branched from the downstream of the throttle to bypass the main valve, and a fail valve opening and closing the fail passage. The switching valve is arranged on the upstream of the pressure control valve in the pilot passage. The fail passages are branched from the upstream of the switching valve of the pilot passage.
