HOERBIGER Automation Technology Valve Automation: Electrohydraulic valve actuator with an electric ‘look & feel’

2013 German Industrial Valve Trade Show (DIAM) Next Generation of Valve Actuators: TriVAX - Compact, Robust, Powerful and Fast The improved electrohydraulic valve actuator TriVAX made by HOERBIGER is a trendsetter in the process industry. This valve actuator, which has an entirely new design, will take center stage at the 2013 DIAM in Hall 1, Booth B8. TriVAX is the alternative concept to the complexity of conventional actuators and facilitates utilization as a whole, from installation to commissioning to maintenance. It allows users to operate their systems easily, cost-effectively and reliably. "In the future, systems will no longer be as complex as in the past", explains Marcus Grödl, Head of the Valve Automation Business Segment of HOERBIGER Automation Technology. This will benefit the process industry in particular: the improved electrohydraulic valve actuator TriVAX is as easy to install and handle as an all-electric drive unit, yet is as powerful, robust and durable as an actuator that is entirely hydraulic. The intelligent electronics assure simple and intuitive operation. The integrated compact design makes it possible to combine the advantages of three worlds of technology. TriVAX is the name of the game. 'Tri' denotes the optimal blend of hydraulics, mechanics and electronics, and 'VAX' is the abbreviation for 'valve actuator', which offers versatile benefits for the customer. TriVAX is setting a new standard in valve automation when it comes to efficiency increases and upgrades of existing systems, especially in safety-oriented industrial applications, in power plants, and in the oil and gas industry. TriVAX replaces conventional valve control units, which may not yet feature safety functions such as “Emergency Shut-down” or explosion protection and do not comply with the latest standards. Conventional actuators consist of entirely separate hydraulic, mechanical and electrical systems. The individual components are connected by interfaces and cables. These complex systems are often maintenance-intensive and moreover are prone to failure and leakage. "TriVAX is an electrohydraulic valve actuator that has an electric 'look and feel'," emphasizes Marcus Grödl. "It is as easy to install and handle as an electric drive. Because of its compact and closed design, the maintenance interval has been extended to five years. This way, we ensure considerably higher economic efficiency over conventional valve actuators. TriVAX is impressively demonstrating this with projects in power plants, pipelines and in industry."

Compelling details In addition to direct operation using the integrated electronics of the TriVAX unit featuring an intuitive human-machine interface, the valve can also be actuated via a remote control console. Thanks to integrated interfaces to standard field buses (in preparation: Profibus PA, HART, Foundation Fieldbus), TriVAX can also be incorporated into existing automation concepts. The intelligent system requires only a simple electric pulse to start the TriVAX. Marcus Grödl says: "Operators of pipelines are able to control the butterfly valves, which often times are located miles apart, with a TriVAX valve actuator using a simple electric signal." With its flame-proof encapsulated housing, the HOERBIGER TriVAX valve actuator also assures safe operation in areas that are prone to explosions (Ex protection according to ATEX II2GD Ex d IIB T4). Additional functions such as "Quick Action" or "Emergency Shut-down" are also important for the process industry. This makes the TriVAX valve actuator suitable for demanding applications in power plants and in systems of the natural gas, oil and chemicals industries. "Thanks to its high-capacity hydraulics, the TriVAX valve actuator is powerful and easy to operate for the user," says Marcus Grödl. "Because of its simple and piping-free design, it is singularly reliable."
