The SV Type Pressuriser Safety Globe Valve (PORV) ensures stable and precise pressure relief in nuclear applications. Designed for pressuriser safety, it operates via solenoid, spring-loaded pilot, or motor-operated pilot valves. Built from forged or cast carbon and stainless steel, it supports water, steam, air, and hydrogen applications. Featuring controlled opening and closing speeds, linear lift characteristics, and set point accuracy of ±1%, it ensures no chattering or inadvertent opening. With an integral valve position indicator for remote monitoring, the SV Type PORV is ideal for critical safety operations in nuclear plants.
