Mechanically attached connections for conduits may include a conduit gripping member and first and second connection members. The first and second connection members may be, for example, a nut member and a body member where the connection members cause axial movement of the conduit gripping member to grip and seal the conduit when the assembly is pulled-up. The mechanically attached connection may include a sensing function for detecting or sensing a condition or characteristic of at least one of the following: the mechanically attached connection, one or more of the connection members, the fluid contained by the mechanically attached connection, or a combination thereof. The sensing function may be, for example, a sensor that is integrated with at least one of the nut member and the body member.

Conduit connection with sensing function

A ball valve includes a body having a passageway there through with a ball member disposed in the passageway and mounted for selective rotation between valve open and valve closed positions to control fluid flow. A pair of flange grooves are provided in the body on opposite sides of the ball, each flange groove extending radially from the passageway. A pair of seat rings are disposed in the passageway on opposite sides of the ball. Each seat ring has a first sealing surface in contact with an outer surface of the ball and a radially extending annular flange or tab received in an associated one of the flange grooves. The seat design further includes a pair of annular flange seals each disposed in a respective one of the flange grooves. The seat configuration achieves a cantilever effect to improve the temperature and pressure cycling performance of the valve.

Ball valve seat seal

A ball valve ( ) includes a body (A) having a passageway ( ) extending therethrough with a ball member (B) disposed in the passageway and mounted for selective rotation between valve open and valve closed positions to control fluid flow through the valve. A pair of flange grooves are provided in the body on opposite sides of the ball. each flange groove extending radially from the passageway. A pair of seat rings ( ) are disposed in the passageway on opposite sides of the ball. Each seat ring has a first sealing surface ( ) in contact with an outer surface of the ball and a radially extending annular flange or tab ( ) received in an associated one of the flange grooves ( ). The seat design further includes a pair of annular flange seals ( ) each disposed in a respective one of the flange grooves. The seat material is preferably made of a relatively harder and stiffer material compared to PTFE, such a PEEK The seat configuration achieves a cantilever effect to improve the temperature and pressure cycling performance of the valve. The flange seals are energized and made of an elastomer material or other suitable flexible seal materials having spring-like characteristics.
