Abstract
A pressure relief valve control system provides a method and apparatus for rapidly closing a relief valve in response to excess fluid pressure. The system uses a programmable controller to rapidly communicate pressure changes to a solenoid actuated valve and two control valves. The solenoid actuated valve has a dedicated accumulator and the two control valves have another dedicated accumulator.
