Patent number: 6240946Abstract: A switch valve 10 is provided with an upper body 14 having a plurality of outlet ports 20A, 20B, and 20C and a lower body housing 16 with inlet port 18. The switch valve includes a ball member 22 which is rotatable within the switch valve body 12 for selective fluid communication between the inlet port 18 and the selected one of the plurality of outlet ports. The ball 22 is rotated by a stem 28, which may be powered by an actuator unit. The upper body 14 includes a substantially dome-shaped seating surface 40 for sealing engagement with the outer surface 38 of the ball. The biasing member 48 biases the ball radially in a direction opposite the ball inlet port 24 to obtain the desired sealing engagement. The biasing member is preferably a Belleville spring 48 having a single wrap design.Type: GrantFiled: September 17, 1998Date of Patent: June 5, 2001Assignee: Tyco Flow Control, Inc.Inventor: Marvin E.

Patent number: 5313976Abstract: A top entry floating ball valve (10) and method of assembly including a downstream metal seat (62) mounted within an annular recess about a downstream flow passage (22) and an upstream metal seat (80) urged by a Belleville spring (78) into engagement with ball closure member (24). Ball closure member (24) is urged by Belleville spring (78) into sealing relation with downstream metal seat (62). A smooth planar wall surface (16) is defined by valve chamber (14) about the inlet flow passage (20) and Belleville spring (78) may be easily inserted within the valve chamber (14) along smooth planar wall surface (16) behind upstream metal seat (80). Upstream metal seat (80) has an inner spherical surface (82) conforming to the outer spherical surface (26) of ball closure member (24) and may be easily moved manually along the spherical surface (26) for assembly and disassembly.Type: GrantFiled: July 26, 1993Date of Patent: May 24, 1994Assignee: Keystone International Holdings, Corp.Inventor: Marvin E.

Patent number: 5269347Abstract: An isolator flow control apparatus (10) especially to selectively control communication of a contained fluid to an overpressure protection system. The isolator apparatus (10) includes a flow housing (12) having a single inlet opening (20) placed in fluid communication by an internal manifold means with a plurality of outlet openings (22, 24). A floating rotatable ball closure member (28, 30) is operably disposed in each of the outlet openings (22, 24) for effecting a metal-to-metal seal with a fixed downstream seat (16d, 18d). The ball closure members (28, 30) are interlocked by a shaft (34) in a passage (14b) extending between enlarged diameter portions (22a, 24A) receiving the ball closure members (28, 30). The ball closure members (28, 30) are actuated by an operator means (40) for automatically closing or isolating a selected outlet opening (22 or 24) while opening another outlet opening (22 or 24) to ensure continuous fluid flow or fluid communication through the isolator apparatus (10).Type: GrantFiled: December 22, 1992Date of Patent: December 14, 1993Assignee: Keystone International Holdings Corp.Inventor: Marvin E.

Patent number: 5139229Abstract: A ball valve (10) has a one-piece valve body (12) with a small diameter bore (16) and an opposed large diameter bore (18) in fluid communication with a valve chamber (14). An annular flange (40) projects within the large diameter bore (18) and a washer-type square spring (50) is inserted within the central opening (44) defined by the flange (40) and then positioned in centered relation on the shoulder (42) defined by the flange (40) for urging the ball valve member (24) into seated position against an annular seat (22) about small diameter bore (16).Type: GrantFiled: November 18, 1991Date of Patent: August 18, 1992Assignee: Keystone International Holdings Corp.Inventor: Marvin E.

Patent number: 5097635Abstract: Disclosed is a new and improved method and apparatus for automatically lapping a ball and a seat of a valve to produce a non-flat lapped sealing surface finish that provides a reliable fluid seal at minimum cost. Either the seat or ball is rotated as the work piece by the apparatus while in contact with the surface of a lap member which may be the mating seal part. The lap member is held or maintained in a desired angular or tilt relationship with the work piece. A controllable force spring is provided to maintain the desired lapping force between the work piece and lap member. While the lap member is blocked from rotation about the tilt angle and apparatus swings or oscillates the lap member about the work piece to maximize the effectiveness of the lapping contact.Type: GrantFiled: August 6, 1990Date of Patent: March 24, 1992Assignee: Keystone Valvtron, Inc.Inventor: Marvin E.
