摘要： An apparatus for determining when an operational opening event occurs for a pressure relief valve. The apparatus includes a pressure relief valve lift indicator disposed adjacent to a portion of the pressure relief valve to determine the frequency of the operational opening events of the pressure relief valve. A method of monitoring a pressure relief valve. A pressure relief valve lift indicator is placed in close proximity to the pressure relief valve to determine when the pressure relief valve experiences an operational opening event. Operational data associated with the operational opening event is tracked.

摘要： This disclosure is related to a non-electronic pressure control system for a pressurized system that receives fluid from a fluid supply. The pressure control system includes a control module, an actuator and a flow control device. The control module monitors the pressure of fluid either upstream or downstream of the flow control device. The control module can send a pneumatic signal to the actuator to open or close the flow control device responsive to the pressure monitored by the control module and the pressure required for the pressurized system.
