Neles BWX butterfly valve for process industries

Metso’s Neles BWX butterfly valve meets challenging requirements of various process industries. In addition, Metso has delivered its BWX valves to the Siemens Purified Terephthalic Acid (PTA) plant in Netherlands for use in the plastic bottle manufacturing process. BWX valves are also securing process performance for one of the largest LNG customers in China, and for refining customers in India. Originally developed for the oil and gas industry in close collaboration with the gases and engineering company Linde, the valve has immediately proven its performance in a greenfield project for an air separation unit.

Metso’s BWX valves delivered to Siemens’ PTA project have fulfilled the stringent safety and efficiency requirements existing in the demanding oxidation process of PTA production.

The quick-closing Neles BWX butterfly valve is designed to meet the new oxygen service requirements. The valve has a high Cv 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 degrees.
