Claims

[Scope of utility model registration request]

In a gate valve in which a wedge-shaped valve body enters and exits in and out of a valve body, a foot roller portion is formed on the inner surface of the valve flow path that gradually deepens eccentrically with respect to the inner surface of the bore diameter as it ascends from the bottom to both sides, and The molded valve body has a replaceable Teflon body that covers the front and back surfaces thereof in a ring shape, and the Teflon body has an outer circumferential surface along the bottom surface of the foot roller portion and an arc-shaped protrusion along the lower part of the inner surface of the aperture. A no-residue gate valve is also characterized by being eccentrically formed.
