  • Publication number: 20120012768
    Abstract: A flow control valve includes a body having a body bore oriented coaxially with a longitudinal axis of the body and a seat member extending into the bore. A valve member is slidably disposed in the bore and oriented coaxially with the longitudinal axis of the body. The valve member includes a non-circular geometrically shaped head having a bore. A drive adapter includes a head receiving cavity slidingly receiving the geometrically shaped head of the valve member and preventing axial rotation of the valve member. A stepper motor is connected to the drive adapter, the stepper motor incrementally rotating a shaft engaged with the bore of the valve member. First and second equal diameter pistons of the valve member provide pressure balanced valve member operating positions.

  • Publication number: 20110179946
    Abstract: A proportional pressure controller includes a body having inlet, outlet, and exhaust ports. A fill valve communicates with pressurized fluid in the inlet port. A dump valve communicates with pressurized fluid from the fill valve. An inlet poppet valve opens by pressurized fluid through the fill valve. An exhaust poppet valve when closed isolates pressurized fluid from the exhaust port. An outlet flow passage communicates with pressurized fluid when the inlet poppet valve is open, and communicates with the outlet port and an exhaust/outlet common passage. A fill inlet communicates between the inlet passage and fill valve, and is isolated from the outlet flow passage, exhaust/outlet common passage, and outlet and exhaust ports in all operating conditions of the controller.

  • Patent number: 7735518
    Abstract: A solenoid actuated valve assembly includes a valve body having a slidable main valve member and a pilot valve body mechanically connected to the valve body including a slidable pilot valve member. A first solenoid operated valve connected to the pilot valve body when energized directs pressurized fluid to move the pilot valve member between pilot valve open and closed positions. A second solenoid operated valve connected to the valve body when simultaneously energized with the first valve directs the fluid to move the main valve member between valve closed and open positions. A third solenoid operated valve connected to the pilot valve body when energized and when both the first and second solenoid operated valves are de-energized directs the fluid to move the pilot valve to the pilot valve open position and the main valve member to the valve closed position.

  • Publication number: 20080245427
    Abstract: A valve assembly includes a solenoid can having an internal coil. A valve body connected to the solenoid can includes an inlet port and a first valve seat. An axially adjustable retainer threadably connected to the valve body includes an end portion defining a second valve seat. A homogenous valve member/armature slidably disposed in the valve body moves in the presence of a coil generated magnetic flux between valve closed and valve open positions. A valve member/armature first surface area is in fluid communication with a pressurized fluid through the inlet port. A valve member/armature second surface area is in fluid communication with the pressurized fluid in the valve closed position. The first surface area is equal to the second surface area and the pressurized fluid acts equally on the first and second surface areas defining a pressure balanced condition in the valve closed position.

  • Patent number: 7036522
    Abstract: A solenoid actuated pneumatic valve assembly including a valve body having a pressurized air supply inlet port in fluid communication with a source of pressurized air, an outlet port adapted to be in fluid communication with at least one active pneumatically operated device, and a pass-through port. The pass-through port is adapted to be in fluid communication with and provide a pass-through of the supply of pressurized air to the inlet port of at least one other valve assembly such that the valves are mounted in series with respect to the supply of pressurized air. A latching assembly is also provided that is supported upon the valve body and is adapted to engage and be operatively retained within an aperture in a mounting plate.

  • Patent number: 6668861
    Abstract: A pneumatic valve assembly including a valve body having an inlet port in fluid communication with a source of pressurized air and a valve bore extending axially within the valve body with a valve member movable between predetermined positions within the valve bore. The valve member selectively movable to direct a flow of pressurized air from the inlet port through the valve bore to an outlet port. A valve element is disposed upon the valve member having an angular valve sealing surface, and a valve seat is defined in the valve bore formed at an oblique angle to provide a sealing contact with the valve sealing surface when the valve member is in a closed position thereby interrupting said flow of pressurized air.

  • Patent number: 6167600
    Abstract: A columbarium system for the storage of human remains that includes a plurality of similarly configured storage containers is disclosed. The storage container has walls that define an enclosure having an opening at one end with a mounting plate attached thereto. The mounting plate has a pair of tabs that are arranged on opposite sides of the mounting plate and one pair of receiving grooves arranged at opposite sides of the mounting plate. The receiving grooves are dimensioned for receiving a tab from another container so that an arrangement of containers can be formed by the interlocking engagement of the tabs and grooves in adjacently arranged containers. The storage containers are self-framing in that additional framing members are not required for the erection of the columbarium system.
