US 2017/0285668 A1 · PRESSURE RELIEF VALVE APPARATUS AND AN ELECTRONIC SYSTEM FOR CONTROLLING THE SAME

Abstract

Provided are methods and systems for controlling a pressure relief valve. An electronic control unit monitors pressure being supplied from a source. If the control unit determines that the monitored pressure is above a threshold pressure, the control unit controls an actuator to move the pressure relief valve to an open position, thereby releasing the pressure from within the system. If the control unit determines that the monitored pressure is at or below the threshold value, the control unit controls the actuator to move the pressure relief valve to a closed position.

Dependent claims

A system for controlling a pressure relief valve, the system comprising:

an actuator that operates to move the pressure relief valve between an open position and a closed position;
and
a control unit that controls operation of the actuator;
wherein the control unit is configured to:
monitor hydraulic pressure being supplied from a source, and
responsive to determining that the pressure is above a threshold pressure, control the actuator to move the pressure relief valve to the open position.
