First Claim
Patent Images
1. A ball valve comprising:
- a valve body having two ends and a channel extending between the two ends;
a ball located inside of the valve body, the ball having a bore extending through the ball from a first end of the ball to a second end of the ball;
two valve seats, wherein a first seat is adjacent the first end of the ball and a second seat is adjacent the second end of the ball; and
a fitting made of a material different than the valve body integrated into the valve body, the fitting located adjacent and spaced apart from one of the valve seats and extending in a direction along the channel of the valve body, the fitting having a plurality of ribs that are spaced apart in the direction along the channel,wherein the plurality of ribs are configured to prevent translation and rotation of the fitting relative to the valve body, andwherein at least one of the ribs of the fitting is non-axisymmetric relative to an axis extending in the direction along the channel.

Abstract
Embodiments provide a fitting that is integrated into the valve body of a ball valve during the manufacture of the valve body. The fitting and a cartridge may be overmolded to create the valve body. The mold may apply a pressure onto the fitting during the molding process. The fitting may transfer the pressure of the mold onto the cartridge. The fitting may transfer a sufficient amount of force to seal valve seats of the ball valve.

7. A ball valve comprising:
-
a valve body having two ends and a channel extending between the two ends; a ball located inside of the valve body, the ball having a bore extending through the ball from a first end of the ball to a second end of the ball; two valve seats, wherein a first seat is adjacent the first end of the ball and a second seat is adjacent the second end of the ball; and a fitting made of a material different than the valve body integrated into the valve body, the fitting located adjacent and spaced apart from one of the valve seats and extending in a direction along the channel of the valve body, the fitting having a plurality of ribs that are spaced apart in the direction along the channel, wherein the plurality of ribs are configured to prevent translation and rotation of the fitting relative to the valve body, and wherein at least one of the ribs comprises a flat surface on at least a portion of an outer edge of the rib, the flat surface having a width extending substantially in the direction along the channel, the flat surface configured to hinder rotation of the fitting relative to the valve body. - View Dependent Claims (8, 9, 10, 11)
