The invention discloses a valve component for a four-valve diesel, which comprises valve bridges and valves at two ends of each air valve bridge. The top ends of the valves are in contacted connection with the valve bridges, each valve bridge presses down to push the valves at two ends to jointly move down under the action of a rocker, and the valves are open. When down pushing force of the rockers is insufficient to overcome restoring force of valve springs, the valves at two ends and the corresponding valve bridge move up together under the action of the springs, and the valves are closed. A valve height adjusting mechanism is arranged at one end of each valve bridge and enables the valve bridges to keep horizontal and vertical movement in use. The top ends of valve rods can be uniform in height by adjusting the adjusting mechanism at one end of each valve bridge to effectively guarantee vertical movement of the valve bridges, and the two valves controlled by each valve bridge can be stressed simultaneously, so that unfavorable influences of non-uniform top heights of the valve rods caused by manufacturing and fitting problems of the valves can be effectively eliminated.
