Valve Technology

Kalsi Engineering is a critical developer of valve and actuator technology used in US and international Nuclear power plants to determine operational readiness of safety related valves. Kalsi Engineering’s involvement included being the primary model developer of the EPRI PPM high flow gate model and butterfly valve model. Kalsi Engineering has further incorporated these models into our KVAP^®; software.

Our continuous involvement with valve technology has resulted in the development of reliable analytical models, design improvements, and innovative solutions to persistent valve/actuator problems that have defied the industry for decades. Our expertise spans from the conceptual stage through detail design, analysis, prototype development, testing, manufacturing; troubleshooting; and root cause analysis of valve and actuator problems.
