Ball valve manufacturers are required to test the valve torque

The oil and gas industry is involved in the transport of hazardous chemicals. Therefore actuated valves must perform correctly and provide high performance. Comprehensive reporting and documentation for the end-user are of utmost importance. Malfunctioning ball valves and actuators reduce safety during production processes and increase acquisition and maintenance costs significantly.

alkitronic® VTT and ZG are ideal for testing all kinds of valves of all sizes. Our torque testing equipment consists of a sensor torque multiplier, application software and an operation panel. It was customized to test 90° opening and closing cycles of ball valves with a tool torque range of central gear up to 147,500 ft-lbs (200,000 Nm). alkitronic® VTT and ZG outperform international standards of traceability of torque values, quality and reliability. These are the key factors to prevent failures effectively. Smoothly working valves increase productivity as well as plant safety and reduce maintenance costs at the same time. The documentation of torque values helps to identify and avoid threatening risks (e.g. running costs). Moreover, it enables you to prove the necessary torque to move the ball valve with different loads.
