摘要： A system includes a ball valve. The ball valve includes a housing (15), a ball (20), and a first valve seat assembly. The housing (15) includes a chamber, a first fluid passage (28) intersecting the chamber, and a second fluid passage (30) intersecting the chamber. The ball (20) is disposed in the chamber and is configured to control fluid flow between the first and second fluid passages. The first valve seat assembly is disposed between the ball (20)n and the housing (15). The first valve seat assembly includes a first seat (40) configured to seat against the ball (20) both above and below a pressure threshold, and a second seat (42) configured to seat against the ball (20) only above the pressure threshold, wherein the second seat (42) has a coefficient of friction that is lower than the first seat (40).

摘要： A valve having high and low pressure seals. The valve has a housing in which is mounted a valve closing member having a sealing surface which faces an opening in the housing. A low pressure seal surrounds the opening and is biased into contact with the sealing surface. A high pressure seal also surrounds the opening. Pressure in the valve pushes the closing member against the low pressure seal, which moves toward the opening until the closing member contacts the high pressure seal.

摘要： An improved fluid control valve is provided. The valve (10) includes a seal (24) which is captured between an upstream flange adapter (14) and a valve member (18), so that the seal prevents fluid from leaking around the valve member. The seal is carried by a holder ring (26), and stopmembers (40) are attached to the flange adapter for limiting upstream travel of the holder ring at specific points, thereby to restrict tilting of the seal as the valve member rotates.

摘要： A spring for a top entry ball valve includes a generally ''u'' shaped spring body (50A) with an open end. The ball valve includes a valve body (12) with inlet and outlet flow passages communicating with a valve chamber. A ball element (18) is mounted in the valve chamber for rotation between open and closed positions relative to the flow passages. A seal element (40A, 40B) is mounted adjacent each flow passage with a sealing face in opposed sealing relation to the ball element. A movable seat assembly is located between the seal element and the valve body for maintaining the seal element in sealing relation to the ball element. The spring is located between the movable seat assembly and the valve body and is adapted to urge the movable seat assembly and the seal element toward the ball element.

摘要： A system includes an annular ball valve seat (24) including an annular spring (38), which biases the annular ball valve seat axially. More specifically, the annular ball valve seat includes a main body section (32), a lip section (48) extending from the main body section, and a seat groove (36) between the main body section and the lip section, wherein the first annular spring is disposed within the seat groove. A first leg of the annular spring biases the lip section in a first axial direction and a second leg (42) of the annular spring biases the main body section in a second axial direction opposite the first axial direction. The annular ball valve seat is configured to be disposed within a ball valve, on either side of a ball of the ball valve. The particular design of the annular ball valve seat enables pressure within a body cavity of the ball valve to be self - relieving.
