Metso supplies butterfly valves to Siemens acid processing plant in Netherlands

Finnish industrial equipment maker Metso has delivered its Neles BWX valves to the Siemens purified terephthalic acid (PTA) plant in Rotterdam, Netherlands, for use in the plastic bottle manufacturing process.

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 valve body 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 valve has been specifically designed to meet the new oxygen service requirements.

The valve has a high Cv value provided by its metal-seated butterfly design, and 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°.
