MEA INC recently completed a vital upgrade at a leading European steel mill, significantly enhancing the efficiency of their coke oven operation. The Coke Oven Back Pressure Control Valve, responsible for maintaining the pressure inside the coke oven at the appropriate level, was not operating according to the desired process requirements. During each coke unloading process, the back pressure control valve operated by pneumatic actuator failed to react quickly and accurately enough, causing substantial disruptions to the process. In response, the customer upgraded to the MEA Hawk electro-hydraulic actuator, resulting in immediate and substantial improvements. The MEA Hawk efficiently controlled and responded to 0.1% step changes with an impressive 80-millisecond deadtime, delivering 50,000 inch-lbs of torque. Additionally, the unit was equipped with an ESD trip system capable of closing the valve within 2 seconds during emergencies. This upgrade significantly improved plant operations and resolved the existing issues. Beyond the actuator's high performance, the MEA Hawk also provided several additional benefits, including simple installation, high-resolution position feedback, advanced alarming and diagnostics, and convenient calibration via the standard touchscreen HMI. Choose MEA Hawk for unparalleled performance, reliability, and cost-effectiveness in actuation technology for steel mill operations. #actuator #Hawk #coking #electrohydraulic #steelmill #controlvalve

An Eastern USA-based tissue production manufacturer, relying on gas turbines to power its operations, faced a persistent challenge. Despite its intention to contribute excess power to the grid, the existing gas turbine setup struggled to synchronize with the grid, leading to significant revenue loss. Upon investigation by the customer's engineers, the root cause was traced to the turbine's fuel gas control valve. Equipped with pneumatic actuators, the valve couldn’t accurately position itself, resulting in delays and inefficiencies. The existing pneumatic #actuator had excessive deadtime for the application and could only respond to 0.5% step changes, which was not sufficient for this purpose. In response, the customer opted to upgrade to the MEA Hawk electro-hydraulic actuator. The impact was immediate and substantial. Following installation, calibration, and fine-tuning, the MEA Hawk was able to control and respond to 0.1% step changes with an impressive 80-millisecond deadtime. This upgrade not only improved turbine efficiency but also simplified startup procedures, making grid synchronization a smoother process. After years of continuous operation, the MEA Hawk has proven its reliability and dependability, revolutionizing gas turbine fuel control valve performance for the customer. MEA INC #Hawk

MEA INC stands at the forefront of actuation technology for refinery operations, specializing in FCCU/RFCCU catalyst slide valves, expander inlet and bypass control valves. As an approved supplier for major refinery licensors such as UOP and Axens, we bring unmatched expertise and reliability to every project. For years, the industry has relied on hydraulic power control units (HPCU) and hydraulic actuators as the sole dependable solution for operating these valves. However, MEA understands the challenges inherent in such systems. They are complex, occupying significant space on the FCCU deck, and demanding extensive maintenance, including large oil reservoirs, hydraulic runs, filtration, and cooling systems. In response, MEA has developed the MEA Hawk self-contained self-contained electro-hydraulic actuator?as a groundbreaking alternative to traditional HPCU-style systems. With MEA Hawk: ? You receive a lower-cost alternative without sacrificing performance, reliability, or safety. ? Hawk eliminates the need for filter changes and oil sampling, with 80% fewer maintenance items and a modular design that decreases the risk of leaks. ? It requires less space on the deck, consumes less power, and removes the necessity for hydraulic runs around the entire FCCU. ? Training refinery personnel on Hawk is simpler, leading to increased efficiency and reduced downtime. ? The total cost of ownership is dramatically reduced. Since the installation of the first four Hawk actuators on FCCU slide valves in 2020, four years of successful operation have proven their ability to meet all performance requirements, safety standards, and reliability expectations, even in super-critical applications at FCCUs. Additionally, end-users have enjoyed significant reductions in maintenance time and costs. Choose MEA Hawk for unparalleled performance, reliability, and cost-effectiveness in actuation technology for refinery operations. #actuator #FCCU #electrohydraulic #criticalapplications #Hawk #refinery
