PURPOSE: A method, an apparatus, and a system related to a fuel transfer system for industrial equipment are provided to move a cyclic poppet at the position for covering an opening and the position for covering a part of the opening. CONSTITUTION: A method, an apparatus, and a system related to a fuel transfer system for industrial equipment comprise a circular flow check valve(10), a first valve(65), and a second valve(66). The circular flow check valve comprises an inner body(14), an outer body(12), a spring-operated cyclic poppet(24) and an opening(44). The inner body and the outer body divide a concentric channel including an outer channel(16) and an inner channel(18). The spring-operated cyclic poppet is positioned at the outer channel and moves in the axial direction. The opening passes through the inner body connecting the outer channel to the inner channel. The first valve controls the flow of the purge air flowing into the outer channel. The second valve controls the flow of the liquid fuel flowing into the inner channel. |
