Butterfly valve meets requirements of CPI

By Chemical Engineering |

The Neles BWX high-performance butterfly valve (photo) has now gained ground in meeting the challenging requirements of various process industries, including applications in air separation units, liquefied natural gas (LNG) and turbines. In addition, BWX valves have been delivered to Siemems’ purified terephthalic acid (PTA) plant in Rotterdam, the Netherlands, for use in the plastic-bottle manufacturing process. The body of the BWX has a monolithic design without a clamp ring, which is optimal for high safety and reliability in use, as there are no additional parts or screws that could detach. The quick-closing butterfly valve has been specifically designed to meet the new oxygen service requirements. The valve has a high C v value provided by its metal-seated butterfly design. As a result of the unique sealing system, the valve can perform even with a critical pressure ratio and at an operating angle as small as 10 deg. — Metso Corp., Helsinki, Finland
