<p>A needle valve (20) that adjusts the flow of liquid fluid and an open/close valve that makes it possible to fully close a flow path of the liquid fluid are accommodated inside a casing of a flow adjusting valve (1). The needle valve (20) is provided with a reciprocating movement section (40) that adjusts the flow of the liquid fluid by moving a needle valve piece (21) toward and away from the valve seat (13). The open/close valve (30) is provided with an opening/closing section that utilizes a basal outer surface of the needle valve piece (21) facing the valve seat (31) as a fully-closing valve piece (31) and that reciprocatingly moves the fully-closing valve piece (31), independently of the reciprocating movement section (40), between a closed position, where the fully-closing valve piece (31) is in close contact with the valve seat (13), and an open position, where the fully-closing valve piece (31) is moved away from the valve seat (13).</p> |
