  • Patent number: 9535427
    Abstract: Temperature-controlled pressure regulators are described. An example temperature-controlled pressure regulator described herein includes a regulator body having a process fluid inlet fluidly coupled to a process fluid outlet via a first passageway and a heat transfer medium inlet to be fluidly coupled to a heat transfer medium outlet via a second passageway, where the heat transfer medium inlet is integrally formed with the regulator body. A heat chamber body is removably coupled to the regulator body to form a chamber between the heat transfer medium inlet and the heat transfer medium outlet. At least a portion of the first passageway is disposed within the chamber, and the chamber is to receive a heat transfer medium via the heat transfer medium inlet to provide heat to the process fluid as the process fluid flows through the chamber via the first passageway, which separates the process fluid from the heat transfer medium.

  • Patent number: 8991427
    Abstract: A high pressure three-way control valve comprises a valve body defining first, second, and third ports disposed in selective fluid communication with each other via a control element. The control element is movable between a first seated position and a second seated position to selectively control the direction of fluid between the first and second port, or alternatively, between the first and third port. So configured, the control valve serves a function that conventionally requires two valves plumbed together.

  • Patent number: 8757199
    Abstract: A control assembly for a fluid flow control device includes a control element, a load spring, and a spring clip. The control element can be movably disposed for controlling fluid flow, and the load spring biases the control element into a predetermined position. The spring clip contacts the load spring at a plurality of points to dampen vibrations experienced by the load spring, thereby reducing and./or eliminating resonance. The spring clip includes a body plate and first and second opposing arm plates extending away from the body plate. Each arm plate includes a proximal end adjacent the body plate, a distal end spaced away from the body plate, and a finger extending upwardly away from the distal end. A corner at an intersection between the finger and the distal end includes a contoured edge for facilitating attachment of the load spring to the spring clip.
