HOUSTON -- The US Patent and Trademark Office has awarded Mogas industries’ John Williams and Vinh Nguyen a patent for a thermally compensated mounting flange.
The two engineers designed a mounting flange that is constructed from 410 stainless steel and an engineered precision cut. The cut allows the flange to grow and flex without causing damage to the valve, while maintaining precision alignment of the valve stem and actuator. The result is a cost savings for the customer without jeopardizing the valve or the facility using the valve, the company says.
“The thermal expansion issue creates undue stresses on the flange and the valve,” says Nguyen, director of technology and research and development for MOGAS. “By using a less expensive material for the mounting flange and incorporating the slit in the flange we have found a way to reduce the cost, reduce the thermal stress, and provide a sound answer to the challenge we were presented.”
