Our online test has a double-action hydraulic device that, when coupled to the valve body and stem, is slowly activated exerting force against the valve closure until the actuation is verified.

During this process, a combination of sensors monitors various parameters relevant to the valve's behavior. The information is cross-referenced and presented in a real-time graph, relating the collected information, such as calibration parameters and technical valve construction standards. After the complete test and calibration cycle, the obtained information is archived and related in the test report and calibration certificate provided to the customer.

The online test is a nautical instrumentation tool used to assess the opening point of safety valves. The tool is based on the principle of the balance of 3 forces: Process; Spring; Hydraulic Device. At the moment when the 3 forces have a null resultant, the movement of the shutter is verified, causing the valve to open. Always be attentive: As the process force is the result of the product between the fluid pressure and the internal area of the valve seat, make sure that this area and pressure information have been obtained from secure sources. Also, check for the presence of acoustic sensors capable of identifying the exact moment of equipment opening and always demand the presentation of load cell calibration certificates.
