Severn glocon, a professional control valve company, will use Metso's intelligent positioner to meet the strict requirements of the LNG project for anti surge valves. The two companies worked together to successfully overcome various technical challenges, such as ensuring that the valve opened within one second of receiving the signal. The customized Metso Neles nd9000 positioner greatly enhances the reliability and repeatability, so that the valve meets the strict requirements of factory testing and calibration. The increasing operating requirements of the LNG industry increasingly drive the use of more sophisticated methods for valve calibration. Such as smart locators that require fine tuning to achieve optimal performance. This requires professional technology and intelligent engineering design. The application of anti surge is the key to the successful and safe operation of compressor. When the fluid flows back instantaneously, surge may occur due to pressure instability. This will damage the equipment, cause potential hazards, and lead to plant downtime at a high cost. In order to avoid this situation, Chinese farmers are willing to work hard to install high-performance anti surge control valves between the exhaust port and the air inlet of the compressor. When potential surge is detected, quickly open the valve to transfer pressure. "Our positioner includes a detection function called" capture ", which can recognize the movement of the valve assembly and keep it stable during the main movement. This function was too intense at the beginning. 2. Press the displacement and landing keys, so we replaced the firmware triggered by it. In the frequency response test, the valve assembly needs to be fast enough to respond to the process change without damaging the response of the scraped test body speed, and our positioner performs extremely well.
