<p>A valve body for a valve includes a body (3) having an internal cavity (13) formed therein. An inlet passage (27) and an outlet passage (31) are formed in the body (3). ________________________ The inlet passage (27) has an inlet opening (21) in communication with the internal cavity (13),and the outlet passage (29)____ has an outlet opening (23) in communication with the internal cavity(13). A circumferential sealing surface (37) is formed on a wall of the internal cavity(13). The circumferential sealing surface (37) extends between the inlet opening(21) and the outlet opening (23) and circumferentially around the internal cavity (13). Furthermore, a bottom line extending through the inlet passage(27), the internal cavity and the outlet passage (29) forms a coplanar surface (20) to allow for free-drainage of the body.</p> |
