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. Beasley

Patent number: 6192924Abstract: A pilot operated safety relief valve (14) in which a pilot valve (32) controls the opening and closing of the main valve member (26). The pilot valve (32) has a spindle valve member (70) between an intermediate dome fluid chamber (52) and an exhaust chamber (54) communicating with exhaust port (52) and exhaust line (38). Spindle valve member (70) has an annular sealing member or membrane (104) having a relatively thin body (105) with opposed beads (106, 108) along inner and outer peripheries of body (105) for sealing between spindle valve member (70) and the adjacent retainer sleeve (94). Any positive backpressure forces from exhaust line (38) are balanced against spindle valve member (70) by annular seal (80) and membrane (104).Type: GrantFiled: January 19, 2000Date of Patent: February 27, 2001Assignee: Tyco Flow Control, Inc.Inventors: Michael D. McNeely, Thomas F. Higgins

Patent number: 6161570Abstract: A pilot operator and a relief valve are provided in the same housing. The pilot-operating mechanism is contained partially within the main closure element of the valve and partially within the valve cap. Inlet pressure to the valve is communicated to the pilot via an access passage extending through the main closure element. In response to high-pressure flow from the inlet, a pilot piston moves a spacer rod through the passage and into engagement with a spring-loaded vent closure. The piston-induced movement of the rod opens the vent to relieve the pressure behind the main closure element, which in turn permits the main closure element to open and relieve the inlet pressure through the valve outlet. Opening of the main closure element terminates flow through the access passage. When the inlet pressure is sufficiently reduced, the pilot piston is unseated by the spring force re-opening the access passage to allow the pressure behind the main closure element to increase and close the main closure element.Type: GrantFiled: June 1, 1999Date of Patent: December 19, 2000Assignee: Tyco Flow Control, Inc.Inventor: Michael D. McNeely

Patent number: 5967165Abstract: A valve body with a diverted flow passage extending between the inlet and the outlet is provided with a closure element that is mounted between the inlet and outlet and movable between first and second lift points for regulating fluid flow through the passage. A baffle disposed in the flow passage intermediate the first and second lift points alters one or more flow characteristics of the fluid to improve the efficiency of fluid flow through the valve. In a right angle body valve, the baffle takes the form of a plate with an aperture positioned concentrically with the inlet passage and the valve closure element. A top plane surface of the baffle plate is positioned below the centerline of the outlet and is perpendicular to the centerline of the inlet. The baffle separates turbulent areas of flow in the passage so that the pressure and flow of fluid exiting the valve are more uniformly distributed over the entire outlet.Type: GrantFiled: December 19, 1997Date of Patent: October 19, 1999Assignee: Tyco Flow Control, Inc.Inventor: Jack B. Alberts

Patent number: 5934645Abstract: A rotary valve is provided including a valve element mounted within the flow path of a valve body and rotatable about a stem axis. A peripheral seating surface on the valve body surrounds the flow path through the valve body and is spaced from the stem axis for sealing engagement with the valve element when rotated to its closed position. The peripheral seating surface on the valve body is preferably annular, and more preferably has an arcuate cross-sectional configuration and includes a central annular seating line spaced closer to the center point of the valve than adjoining upstream and downstream portions of the seating surface. The valve element includes a rigid body with a peripheral resilient overlay. The resilient overlay has a peripheral pressure-responsive sealing member for flexing in response to fluid pressure into sealing engagement with the seating surface.Type: GrantFiled: May 11, 1998Date of Patent: August 10, 1999Assignee: Tyco Flow Control, Inc.Inventor: Douglas G. Calvin

Patent number: 5848607Abstract: A mounting plate is disclosed that is adapted to be positioned between a main flow line and at least two differential pressure transmitters, to place the two differential pressure transmitters in fluid communication with a pair of pipeline taps on opposite sides of a flow reducing orifice plate in the main flow line is disclose. The mounting plate includes a plate-like body generally rectangular in cross section along its longitudinal axis and longer than it is wide along its transverse axis. The plate-like body includes a pair of ports that extend through the body and are in fluid communication with the pair of pressure taps with the longitudinal axis of the body parallel to the main flow line. A plurality of passageways or bores extend into the body to connect the ports to various combinations of pressure transmitters.Type: GrantFiled: May 30, 1997Date of Patent: December 15, 1998Assignee: Tyco Flow Control, Inc.Inventors: Joel David Bell, Alan Fu Chou
