Abstract: Used gas lift valves having a used bellows assembly are remanufactured. Separable components are disassembled, and the used bellows assembly is removed from a dome housing by de-brazing the used bellows at a brazed joint from a mating surface of the dome housing. A replacement bellows is then affixed (e.g., arc welded) to the dome housing's mating surface, and a bellows adapter is affixed (e.g., arc welded) to the replacement bellows. The separable components of the used valve are then reassembled to produce a remanufactured gas lift valve. The remanufactured valve has a replacement bellows composed of a nickel-chromium alloy as opposed to a nickel-copper alloy, has the replacement bellows arc-welded to the dome housing as opposed to being brazed thereto, and has the adapter arc-welded to the bellows as opposed to being brazed thereto.

Abstract: The present invention comprises a valve assembly with an unbalanced seal between sealing components of the valve assembly. For a gate valve assembly, an upstream seat may have a different outer diameter than a downstream seat, thereby creating an unbalanced seal with the gate. By increasing the sealing surface of the downstream gate/seat interface and by decreasing the sealing surface of the upstream gate/seat interface, the gate/seat interface may seal at lower pressures. A bidirectional seal is also disclosed that may prevent grease or sand from entering a cavity of the seat/pocket insert interface and assists with controlling the pressures and torque on the valve assembly.

The coupler is configured to receive an electrical signal to constrict a flow of the coolant liquid.

Abstract: A novel valve device and related method of using that can provide for real-time pressure control adjustments and accurate meter reading when installed in a waterline. A two-stage pressure control system can comprise a dual-spring mechanism engineered for precise and adaptive water flow regulation. Water can enter the valve through the one or more inflow ports at an inlet end, travel through the body, and exit through the one or more outflow ports at an outlet end or through side windows in the valve body for certain embodiments. As a result, the dual-spring mechanism can generate backpressure. When water mixed with air flows through the waterline, the valve can create backpressure upstream causing the air at or near the meter to compress for a more accurate meter reading.
