Abstract: A pressure relief device and a hydraulic fracturing system having a pressure relief device are provided. In one form, the pressure relief device has a valve body with a linearly extending throughbore between the inlet and outlet thereof. A rupture disc is secured in the valve body so that a frangible dome wall portion thereof has a reverse-acting orientation in the valve body bore. The hydraulic fracturing system includes a pump and a delivery line that receives pressurized fracturing fluid from the pump and delivers it to a well. A pressure relief device is installed along the delivery line. A sensor detects fluid flow downstream of the pressure relief device which allows the pump to be shut down when the downstream fluid flow is detected. The pressure relief device can have a body with a domed rupture disc and the sensor therein.

Abstract: A rupture disc valve device as provided herein is configured to selectively release a pressurized material. In some embodiments, the rupture disc has a burst pressure rating less than a pressure of the pressurized material. The valve device selectively braces the rupture disc until release of the pressurized material is desired. To release the pressurized material, the valve device is configured to remove or adjust the bracing support to the rupture disc, allowing the pressurized material to burst the rupture disc.
