ABSTRACT:
A valve having a purging apparatus includes a valve body having a defined passage that is aligned along an axis of the valve body. A conduit having an axis passing downwardly through the valve body and in communication with the passage forms an angle with the axis of the valve body. A slit is formed in the valve body about the axis of the conduit to establish a housing integral with the valve body. The slit surrounds and isolates the housing and a portion of the conduit from the valve body to a given depth and includes a depth and a width such that the housing is isolated from stresses induced in the valve body. A tubular element is joined to the housing in axial alignment with the conduit and is inserted to a depth that is less than the given depth of the slit. The valve is purged through the tubular element via the conduit.
