    Abstract: A pilot-operated pressure relief valve nozzle assembly and associated systems and methods are provided. In an exemplary embodiment, the nozzle assembly includes a body having an elongate shaft with an inner lumen extending therein and a flange at one end of the elongate shaft and having an annular notch formed therein. The annular notch is configured to seat an annular ring, and the annular notch includes an annular groove formed therein that enables communication between a first bore extending through the flange from the inner lumen to the annular groove and a second bore extending through the annular ring, thus allow the first and second bores to be radially offset from one another.

    Abstract: A tool configured for use to assemble and install trim into a steam conditioning valve. These configurations can include a device that mounts in place of a bonnet and an actuator that technicians remove from the valve. The device can cantilever the trim assembly, essentially providing a platform on which technicians can slide the trim assembly into the valve body (or out of the valve body) to complete install or repair of the device. As an added benefit, technicians can also use the device to assemble the trim in proximity to the subject valve.
