Abstract
A pilot operated pressure relief valve includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. A valve plug may be disposed within the fluid passageway, the valve plug cooperating with a valve seat to control fluid flow through the fluid passageway. An actuator may be connected to the valve plug, the regulator biasing the valve plug towards the valve seat. A pilot assembly may include a first pilot valve and a second pilot valve, wherein the pilot assembly directs fluid pressure upstream of the valve plug to one of the first and second pilot valves. When the upstream fluid pressure exceeds a predetermined level, the valve plug moves away from the valve seat allowing fluid to flow through the fluid passageway.
