Emerson has announced that the Sempell™ 181 control valve has successfully passed the NAMUR type test NE 95. Compliance with NE 167 has also been confirmed. The tests were carried out in conjunction with the company’s own Fisher™ FIELDVUE™ DVC7K digital positioner.
The test was carried out by Tectrion GmbH. The results demonstrate that the valve is suitable for use in the process industry. The tests examined, amongst other things, leak tightness, performance under pressure and behaviour during temperature fluctuations ranging from -40 °C to +80 °C and up to 200 °C. In total, the control valve completed 100,000 switching cycles. Even after completion of these stress tests, the required tightness values were not only met but, in some cases, significantly exceeded.
The successfully completed NAMUR type test NE 95 and conformity with NE 167 are regarded as important benchmarks for the practical suitability of components in the process industry. This provides independent confirmation that the valve meets the high requirements of chemical, petrochemical and other industrial applications.
Focus on safety and reliability
The Sempell 181 is specifically designed for applications where operational safety and reliability are of paramount importance. Its design allows maintenance work to be carried out on the actuator without any risk of process media escaping, thereby enhancing workplace safety. Furthermore, the valve complies with the requirements of ISO 15848-1 regarding fugitive emissions and is compatible with both pneumatic and electric actuators.
“German chemical companies expect proven performance under realistic conditions,” explains Antonio Alonso, Director of Strategic Product Business Units, Flow Controls Europe at Emerson. “The independent confirmation of NAMUR type approval NE 95 and conformity with NE 167 underscores that the Sempell 181 meets the tightness, durability and latest emission guidelines that customers can rely on for critical applications.”
