  • Patent number: 8794588
    Abstract: An actuator regulating valve apparatus comprising an actuator assembly operably installed within a valve body assembly, a bellows assembly operably installed adjacent to the actuator assembly, a biasing assembly operably installed on the valve body assembly substantially opposite the bellows assembly and configured to bias the apparatus closed, and a non-compressible liquid filling the apparatus about a bellows of the bellows assembly and the effective working surface of a piston of the actuator assembly and communicating therebetween through an orifice. Alternatively, an actuator rolling diaphragm is configured so as to partially cover the piston and to have a convolution loop supported by a U-shaped insert within a groove about the piston. Further alternatively, a balancing diaphragm sub-assembly of the biasing assembly acts on a pushrod of the actuator assembly to produce a force substantially equal and opposite to the pressure in an inlet side of the apparatus.

  • Patent number: 8783647
    Abstract: Methods for controlling flow are described herein that include a valve assembly provided and operated to control the flow from a first conduit to a second conduit. The valve assembly includes an actuator housing enclosing an actuator piston and defining a counter-biasing chamber and a first control chamber on the same side of the actuator piston, and a first pressure control port in fluid communication with the first control chamber. A valve is connected to the actuator piston and a bore passes through both the actuator piston and the valve thereby placing a face of the valve in fluid communication with the counter-biasing chamber. The actuator piston includes a first substrate area that defines a portion of the counter-biasing chamber and a second substrate area that defines a portion of the first control chamber where the surface area of the first substrate area is less than the surface area of the valve face.

  • Patent number: 8777131
    Abstract: A springless valve that is used for a liquid sprayer has a body that has an upstream bore that has three parts with increasingly larger cross-sections. A pin portion of a slide/pin combination moves between an open position and a closed position. In the open position, liquid in the first part of the upstream bore flows into inlets in the third part of the upstream bore, through a central passage, to an outlet to a downstream bore. A linearly-moving slide portion on the slide/pin combination fits within a recess in the body, and has resilient arms that engage front and rear radial faces on a narrowed waist on the pin. The arms extend over opposed sides of the narrowed waist, have tangs that lock onto a lower side of that waist, and rigidly connect the slide portion to the pin portion, enabling a user to move the slide/pin combination axially between the open and closed positions.

    Abstract: A balanced port control assembly includes a control element with a valve plug coupled to a valve stem and a pressure sensing labyrinth defined at least partly by the valve plug. The pressure sensing labyrinth provides for fluid communication between a sealing surface of the valve plug and a balancing diaphragm carried internally of the control element. The pressure sensing labyrinth includes at least one pressure sensing passage extending from the sealing surface and into the valve plug along a central longitudinal axis of the control element. So configured, fluid pressure resident on the sealing surface of the valve plug is also resident on the balancing diaphragm such that equal and opposite forces are applied to the control element.

  • Patent number: 8573244
    Abstract: A relief valve assembly to relieve overpressure of a pressurized fluid. In accordance with some embodiments, the assembly comprises a housing with an inlet and an outlet to form a conduit for a pressurized fluid. A normally closed valve member is axially displaceable within the housing to engage a valve seat to prevent a flow of the pressurized fluid along the conduit. A biasing member applies a bias force to the valve member to retain the valve member against the valve seat. A piston within the valve member contactingly engages the pressurized fluid. A mechanically collapsible member resists axial movement of the piston responsive to said contacting engagement of the pressurized fluid. The piston and collapsible member decouple the bias force supplied by the biasing spring member upon the valve member from a force upon the valve member applied by the pressurized fluid, thereby maintaining a bubble-tight seal.

  • Patent number: 8567427
    Abstract: Blowout preventer blocks, each having a channel and plate(s) to close it. The blocks are placed over a pipe through which oil or other fluid is escaping, so that the pipe is in their channels. Alongside the channel in each block are one or more plates, having diameters somewhat larger than the diameter of the channel. Explosive charges propel the plates into the channel to seal it off and stop the leak. When multiple blocks and/or multiple plates in a block are placed over a pipe, the assembly may be referred to as a “Christmas tree.” There are passages that allow the plates to move into place to block the channel. Leading edges of the plates act as male elements that engage female reciprocal ends of the passages to create a seal. Grooves and tunnels in the plates allow fluid to escape into the pipe to ensure a seal.

The gas is conducted around the sealing body 10, so that the gas pressure cannot have an effect on the actuation by way of the hand lever 3. The rear housing part 17, which is located behind the front housing part 16 can be displaced inside the front housing part 16, and has a flow-promoting design, being displaced against the force of the valve spring 8, and specifically with the help of the hand lever 3, so that it now can be actuated independently of the gas pressure with precise metering control.

    Abstract: A valve actuator assembly, counter-biased by a working fluid (or gas) pressure, is disclosed. The valve actuator assembly comprises a valve and a pneumatic or hydraulic actuator. A port is defined axially through the valve and actuator that communicates a working fluid (or gas) pressure acting on the valve face to a counter-biasing chamber inside an actuator housing. This design eliminates, reduces, or overcomes a force acting on a face of the valve by communicating a common working pressure of the fluid (or gas) to a substrate on the actuator with a resultant force vector opposite the valve face.
