Beschreibung
Zusammenfassung:	The utility model discloses a novel low-pressure shuttle valve which comprises a valve body (2), an insertion hole (5) is formed in the valve body (2), and the insertion hole (5) is communicated with at least three channels and a hydraulic stopping opening (6). The novel low-pressure shuttle valve is characterized in that a steel ball (1) which can move left and right is arranged in the insertion hole (5), the hydraulic stopping opening (6) is matched and screwed with a hydraulic stopper (4), due to the fact that the steel ball is reasonably arranged in the valve body (2), the steel ball is pushed left and right by means of pressure oil in the different channels to achieve the function of the shuttle valve, and in addition, a conical opening and a conical opening upper gasket of the novel low-pressure shuttle valve are arranged so that closing and opening of the channels can be better facilitated.
