Valve and Actuator Products & Services

Kalsi Engineering has improved margins on AOVs/MOVs for over 25 years by developing reliable models for predicting performance of all types of valves and actuators commonly used in nuclear power plants.

MOV Actuator Test Stand

The Kalsi Engineering MOV Actuator Test Stand provides an efficient way to verify and calibrate torque output of MOV actuators, providing additional capability over calculated/ published data.

KVAP Software

The Kalsi Valve & Actuator Program (KVAP), is state-of-the-art software that performs design basis calculations for all common linear and quarter-turn AOVs and MOVs in the industry. The KVAP validated quarter-turn models with position-dependant accuracy, which no other software contains, provide substantial margin increases in many applications.

CVAP Software

The Check Valve Analysis & Prioritization software (CVAP) quantifies the rate of degradation of check valve internals, including hinge pin wear and disk stud fatigue, and may be used to prioritize valve maintenance, diagnose problems, improve reliability, and trend inspection results for condition monitoring.

LiFE Software

LiFE software computes the design life of the thrust and torsional components of Limi-torque actuators of type SMB/SB/SBD, ranging from size 000 to size 2.
