Abstract
A flow control valve such as a melt flow control valve includes a cock plug body (,) rotatably arranged in a housing (,) having a single melt inlet port (,) extending axially relative to the rotatable cock plug body (,), and at least two melt outlet ports (,) extending radially relative to the cock plug body (,). The cock plug body has a flow passage including an axially extending inflow portion (,) and at least one radially extending outflow portion (,) to selectively communicate the inlet port (,) with a selected one of the outlet ports (,). The cock plug body (,) further has at least one pre-flooding passage (,) extending from the main flow channel to an opening radially displaced from the outflow portion (,), so that a pre-flooding partial flow of melt can flow from the flow channel into the next outlet port, when the cock plug body begins to be rotationally switched from one to the next outlet port.
