Abstract: A pressure control system configured to automatically monitor and control pressure in fluid lines used in hydraulic fracturing or well stimulation activities is disclosed. The system generally includes at least two valve assemblies each having a valve and a valve actuation system, at least one pressure sensor, and an electro-mechanical control package. These components are configured such that the electro-mechanical controls automate the open and closed positions of the valve(s) via operation of the actuator(s) based on user inputs and information from the pressure sensor. This architecture allows the system to monitor and interpret pressures within the conduit and operate the valve position based on user defined signals and set-points. The valves may be positioned to redundantly monitor the same fluid conduit, or separate fluid conduits, and the system may be configured to enable independent valve positions based on independent user defined set-points or user inputted control signals.

Abstract: A pressure control system configured to respond to high-pressure conditions in a fluid conduit is disclosed. The system generally includes first and second flow restrictors positionable inline on a fluid conduit and configured to block fluid flow in the conduit and respond to a high-pressure event to allow fluid flow therethrough. The first flow restrictor is position upstream from the second flow restrictor and may open to allow fluid flow in response to the high-pressure event. The second flow restrictor provides adjustable flow of fluid therethrough or may open a bypass line in response to the highpressure event to allow unrestricted fluid flow therethrough.
