At TechCal, we specialize in the calibration, testing, repair, and certification of flow and valve actuators, including Pressure Independent Control Valves (PICV) and related control devices. These actuators play a vital role in maintaining accurate fluid flow, pressure balance, and system performance in industries such as HVAC, oil & gas, power generation, marine, construction, and process industries. Over time, actuators may drift, lose accuracy, or fail to respond correctly, leading to reduced efficiency, system instability, and increased operational costs. Regular calibration ensures reliable, precise, and energy-efficient system performance while meeting international standards.
