SV - Main Steam Safety Valve
Main steam safety valve with controlled opening for stable pressure relief.
Stable performance with no chattering or simmering.
Spindle-cover feature prevents instability in phase transitions.
Set point accuracy of ±1% with no drift over time.
Features
The SV Type MSSV Globe Valve provides reliable pressure relief for main steam systems in BWR and PWR nuclear plants. Actuated by system pressure, it operates using solenoid or spring-loaded pilot valves and supports steam, water, air, hydrogen, and two-phase flows. Featuring a unique spindle-cover design, it ensures stable performance during phase transitions. With controlled opening and closing speeds, it reduces dynamic pipe loads while achieving set point accuracy of ±1%. Built from forged/cast carbon and stainless steel, the SV Type MSSV offers remote-controlled relief without requiring a pressure sensing line, ensuring safe and efficient operation.
