Safety/Pressure Relief Valve Technology and Services

Kalsi Engineering’s core experience includes addressing safety and pressure relief valve. Kalsi Engineering has successfully addressed safety/pressure relief valve issues including setpoint drift, seat leakage, and disk instability. Kalsi Engineering has worked with many types of safety/pressure relief valves in a wide array of applications including direct-acting safety and power-operated relief valves on pressurizers in pressurized water reactors, pilot-operated safety relief valves on main steam lines in boiling water reactors, and thermal relief valves on hydraulic actuators.

Technology & Services

Kalsi Engineering technologies and services include:

  • Dynamic model development to predict safety relief valve disk stability.
  • Analytical tools to assess seat sealing robustness.
  • Thermal modeling to assess effectiveness of insulation to address set point drift
