Patent number: 5501427Abstract: A valve appropriate for both shut-off and flow regulation operations is disclosed here. The valve is easy to handle, suffers from low flow resistance in its fully opened state, and offers excellent choking performance. A variety of sizes of the valve can be manufactured in a low-cost manner. The valve comprises a valve seat disposed in the midway of flow passages, and a valve casing which houses the valve seat and the valve element inside. The valve seat has a tilt angle with respect to the direction of the flow of a fluid. The valve element comprises a planar plate as its substrate, and an elongated hole on the back portion of the planar plate. The valve element is held at an initial tilt angle, smaller than the tilt angle of the valve seat, with respect to the direction of the flow of the fluid. A control rod is operative so that the valve element increases its tilt angle from its initial tilt angle.Type: GrantFiled: December 7, 1994Date of Patent: March 26, 1996Assignee: Taimei Kinzoku Kogyo Co., Ltd.Inventor: Masayuki Ando
