“This was achieved by cutting an elliptical cone,” says Hofacker. “When you slice the cone the result is a circle giving you the four completely round offset shape. Now you have a higher Cv which means a smaller nominal diameter. It is friction-free which translates to increased service life and life cycles while it also has lower driving forces, in other words, low torques and smaller actuators.” Ultimately, he said, it delivered an extremely cost-effective valve of which the design success has been proven in practice “It has been applied at the biggest LNG terminal in Europe where serious issues were being experienced with the leaking of triple offset valves. The introduction of this new design has completely stopped all the leaking issues.” The valves were manufactured to operate in extreme conditions and have resulted in the highest performance and maximum economy based on the perfectly rounded sealing geometry. According to Hofacker, the introduction of these valves at various operational sites has led to increased operational safety. “The valves are friction-free on the seat and it reduces the risk of failure. There is no wear on the sealing area and has a longer service life.” The extreme temperature ranges from -270 degrees Celsius to +800 degrees Celcius means the valves can easily handle a large temperature difference. “Our clients have also reported reduced operating costs and reduced maintenance costs,” he says. “Another benefit we have seen is the superior tightness. These valves are bubble-tight even in cryogenic applications.”
