Abstract
The present disclosure provides a hydraulically controlled pressure relief valve without needing a hydraulic power unit. The valve maintains the accuracy of a hydraulically controlled valve by providing a self-contained closed hydraulic system built into the pressure relief valve. For safety, the valve can be kept open to call attention to the cause of the pressure relief valve activation, yet be easily reinstated into full service without replacing expendable components such as shear pins and rupture pins. The invention offers a pressure relief valve with accuracy, cost, and ease of use.
