WebMar 24, 2024 · In the default condition, the pump sends to the component connected to the outlet flow information (PRV closed) and it receives the pressure information in return. This pressure information is compared to the PRV setting, and in case it is higher the PRV opens, and the pump switches its output information from flow rate to pressure. WebThe fluid enters from the equipment to the valve and starts moving out of the system. In case of PSV, when the pressure force becomes greater than the spring force the valve opens instantly and a ‘pop’ sound occurs whereas the PRV opens proportionally to the increasing pressure.
