Abstract
A valve body for a valve includes a body having an internal cavity formed therein. An inlet passage and an outlet passage are formed in the body. The inlet passage has an inlet opening in communication with the internal cavity, and the outlet passage has an outlet opening in communication with the internal cavity. A circumferential sealing surface is formed on a wall of the internal cavity. The circumferential sealing surface extends between the inlet opening and the outlet opening and circumferentially around the internal cavity. Furthermore, a bottom line extending through the inlet passage, the internal cavity and the outlet passage forms a coplanar surface to allow for free-drainage of the body.
Claims36
A valve body for a valve, comprising:
- a body;
- an internal cavity formed in said body;
- an inlet passage formed in said body, said inlet passage having an inlet opening, said inlet opening being in communication with said internal cavity;
- an outlet passage formed in said body, said outlet passage having an outlet opening, said outlet opening being in communication with said internal cavity;
- and
- a circumferential sealing surface formed on a wall of said internal cavity, said circumferential sealing surface sealing between said inlet opening and said outlet opening and circumferentially around said internal cavity,
- wherein a bottom line extending through said inlet passage, said internal cavity and said outlet passage forms a coplanar, horizontal surface to allow for free-drainage of said body.
