| 20110247701 | Actuator Adapter Plate - A valve assembly for use in a piping system includes a valve having an inlet and outlet arranged for connection to the piping system, and further includes a valve body, a control element disposed in a flow passage, and a shiftable valve stem operatively coupled to the control element. Valve packing is disposed about the valve stem and is secured by a retainer assembly. An adapter plate is provided and is attached to the valve body by a plurality of gland bolts, with the adapter plate and the gland bolts cooperating to secure the retainer assembly. An actuator bracket is provided and includes a first portion and a second portion, with the first portion secured to the adapter plate by a plurality of fasteners, and an actuator is secured to the second portion of the actuator bracket by a plurality of fasteners, with the actuator having a control rod operatively coupled to the valve stem. | 10-13-2011 |
| 20110174381 | Fluid Regulator Having Pressure Registration Flow Modifier - A fluid regulating device includes a valve body having an inlet, an outlet, a valve port, and a control element shiftable within the valve body. A control assembly includes an actuator coupled to the control element and includes a diaphragm disposed adjacent a diaphragm chamber. A sense tube has a first end, a second end, and an intermediate portion, the first end positioned to communicate with the diaphragm chamber, the second end disposed adjacent the outlet, and the intermediate portion disposed adjacent an intermediate portion of the outlet. The sense tube includes a shoulder and a flared portion, with the flared portion disposed adjacent the second end. | 07-21-2011 |
| 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 |
| 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 |
| 20100071786 | Pressure Loaded Service Regulator with Pressure Balanced Trim - A gas regulator includes an actuator, a regulator valve, and pressure loading device. The pressure loading device provides a pressure load to a surface of a diaphragm of the actuator to act against a downstream pressure being applied to the opposite surface of the diaphragm and being controlled by the regulator. As the downstream pressure varies and the diaphragm displaces to move a control element to regulate the downstream pressure, the pressure loading device maintains a specified load pressure. The regulator may further include a balanced trim applying a balancing force to offset a force of an upstream pressure on the control element. | 03-25-2010 |
| 20090260697 | Valve Body with Dual Sense Mechanism - A gas regulator includes an actuator, a regulator valve, and a secondary device. Downstream pressure feedback is provided to the actuator and the secondary device via a Pitot tube disposed within an outlet of the regulator valve. The Pitot tube has a first branch having an end connected to the actuator to place the actuator control cavity and diaphragm in fluid communication with downstream pressure within the outlet for maintaining the outlet pressure at an actuator setpoint pressure. The Pitot tube also has a second branch having an end connected to the secondary device to place the interior of the secondary device in fluid communication with downstream pressure within the outlet for responding to changes in the downstream pressure when the outlet pressure diverges from a predetermined normal operating pressure range. | 10-22-2009 |
