The invention relates to a multi-port variable expansion plunger valve. A valve is disclosed having: a body having an upstream end and a downstream end; an inlet orifice; a plurality of passages including: a first outlet passage extending into the main body from the downstream end to a position intermediate the upstream end and the downstream end of the main body; an inlet passage extending into the body from an upstream end of the body, the plurality of passages extending along axes parallel to each other, central axes of the passages being radially and/or circumferentially offset from each other; the body has an upstream end and a downstream end, and an inlet passage is formed in the insert configured for axial movement to: fluidly engage with the first outlet passage to define a continuous fluid passage between the upstream end and the downstream end of the body, where: an output flow rate through the body increases or decreases depending on an axial position of the insert. 本发明涉及多端口式可变膨胀柱塞阀。公开了一种阀，其具有：主体，其
