20100269925 | Self-Aligning Spring Seat for Fluid Regulator and Fluid Regulator Comprising Self-Aligning Spring Seat - A spring seat for self aligning a bias-open or bias-close spring is disposed within a tubular control element of a gas regulator and designed to reduce side loading of the spring, which can cause the spring to prematurely fail. The spring seat can comprise a spring seat adaptor and a seat ring. The spring seat adaptor is fixed inside of the tubular control element and the seat ring is movably mounted on the spring seat adaptor via a ball and socket type joint. The movable seat ring is engaged by the spring and adapted to be self-aligned through three-dimensional displacement relative to the spring seat adaptor via the ball and socket joint. | 10-28-2010 |
20100270490 | ANTI-GRADIENT CUPPED SEAT FOR PRESSURE REGULATOR - A regulator having a valve body defining a flow-path for a fluid and having a valve seat, an actuator casing coupled to the valve body, a control member disposed within the actuator casing and adapted for displacement relative to the valve body and the valve seat for regulating a flow of the fluid through the flow-path by moving between an open position and a closed position wherein the control member engages the valve seat, and a spring operatively coupled to the control member and biasing the control member toward the open position. The control member includes a surface facing the valve seat that is recessed. The recessed surface may be a counter-bore, or may have a convex shape, conical shape, or other appropriate recessed surface. So configured, the regulator displaced improved stability in high inlet pressure, low output pressure, high flow rate implementations. | 10-28-2010 |
20110108146 | Flow Restricted Seat Ring for Pressure Regulators - A control device includes a valve body, a seat ring, and an actuator. The valve body defines a flow-path for a fluid. The seat ring is disposed within the flow-path. The actuator is coupled to the valve body and includes a control member. The control member is adapted for displacement relative to the seat ring for regulating a flow of the fluid through the flow-path. The control member includes a sealing disk adapted to sealingly engage the seat ring and close the flow-path. The seat ring includes a plurality of orifices disposed within the flow-path such that the seat ring prevents at least a portion of the flow of the fluid from substantially perpendicularly impacting the sealing disk. | 05-12-2011 |
20140183384 | Valve Sound Reducing Trim Assembly With Pressure Relief Mechanism - A cage for a control valve trim assembly includes a cage body having an opening at one end and a wall extending from the opening, a plurality of cage openings disposed in the wall, and a pressure relief mechanism disposed in the cage wall. | 07-03-2014 |
20140346384 | Positioning Device for Pressure Regulator - A control assembly for converting a “fail-close” regulator to a “fail-open” regulator, or vice versa, without having to modify or reconfigure a casing of the regulator includes a control member, a central rod, and a spring disposed between first and second spring seats. A regulator including the control assembly includes a valve body and an actuator casing, the valve body defining a fluid flow-path. The control member is slidably disposed within the actuator casing and adapted for displacement relative to the valve body for controlling the flow of fluid through the flow-path. The spring and spring seats are disposed about the central rod, such that the spring biases the control member into a predetermined position relative to the regulator casing. | 11-27-2014 |
20140366970 | VALVE SOUND REDUCING TRIM ASSEMBLY WITH PRESSURE RELIEF MECHANISM - A cage for a control valve trim assembly includes a cage body having an opening at one end and a wall extending from the opening, a plurality of cage openings disposed in the wall, and a pressure relief mechanism disposed in the cage wall. | 12-18-2014 |
20150123024 | Mechanically Retained Valve Seat - A sealing disk mounting assembly for a regulator includes a mounting member adapted to be operatively attached to a tubular member of a control member assembly of a regulator, a disk holder operatively attached to the mounting member, and an annular sealing disk disposed in an annular channel that is formed between the mounting member and the disk holder. The annular sealing disk is mechanically retained between the mounting member and the disk holder by compressive forces. | 05-07-2015 |
20150285402 | FLOW PATH VELOCITY MODIFIER FOR A CONTROL VALVE - A flow path velocity modifier allows a control member of a control valve to operate very close to a seat ring while reducing or eliminating restricted flow areas, which results in greatly reduced flow velocity fluctuations, which results in smoother flow, between the sealing element and the seat ring. As a result, sealing elements made of relatively soft materials may be used without fear of damage from high flow velocities. | 10-08-2015 |
