“…It is similar to one used by Yang et al [30] as per the ASME PTC 25 standards. The components for the experimental system are marked as the supercritical boiler (1), steam separator (2), on-off valve (3), storage vessel (4), on-off valve (5), pressure measuring system (6), isolating valve (7), lift testing device (8), measured PRV (9), silencer (10), quick exhausting valve (11), testing vessel (12), and control valves (13)(14)(15)(16)(17). Saturated steam from a supercritical boiler is stored in a high-pressure vessel, and the PSV is attached to a test vessel.…”

“…In order to maximize reliability, PSV/PRV designs should be as simple as possible [10]. In the event of an overpressure situation, the valve must open at a predetermined pressure, allow flow at a rated capacity, and then close when the system pressure has returned to an acceptable level [11,12]. Various process fluids-including air, water, and other potential corrosive media-must be compatible with PSVs/PRVs [13] A consistent, smooth, and stable operation is also required for various fluids and fluid phases [14].…”

“…Experimental two-phase (i.e., steam-water mixture) pressurized flow and break flow increase system pressure oscillation, cause vibration, and degrade their performance [25]. In addition, lessons learned from the control and combined valve studies are supportive [12] of the need to appropriately size and select PSVs. The success of the experimental program depends on successful operation and testing of the facility in which adequate overpressure protection devices (i.e., PSVs or PRVs) are essential.…”

This study covers the critical concerns related to the sizing, selection, installation, maintenance, and testing of pressure safety valves (PSVs). The aim is to ensure the safety of pressurized systems, hydrostatic transmission systems, and hydraulic plants, including process plants, thermal power plants, and nuclear reactor systems. PSVs are devices that ensure the safety and reliability of pressurized vessels, lines, and systems during overpressure events. The task of selecting which PSV features are of greatest value for a specific purpose is complex—especially in the design of a high-pressure experimental thermal–hydraulic facility for hydrostatic and transient testing of the reactor system—when the systems are in the design and development phases and require qualification and demonstration to prove that they have reached a given level of technological readiness. The present study highlights the required steps for users to follow the associated rules, guidelines, and recommendations. As a part of this research, case studies are presented to help readers better understand the applicable strategy and standards. A discussion and a review of PSV performance degradation and failure are summarized to provide a better understanding of varied process applications and conditions, including fluid flow dynamics, boundary-layer formation and pressure drops, gas bubble formation and collapse, geometric configurations, inlet/outlet piping, abrupt pressure fluctuations, and acoustic resonance. Moreover, this study discusses the servicing and testing of PSVs in a multiphase pressurized system. Overall, it provides a basic overview of how PSVs ensure the safety of pressurized systems, supported by case studies and industrial practices.
