2 Powerful and simple, singularly reliable Piezotechnology in pneumatics successfully applied worldwide, under extreme conditions The secret of the HOERBIGER valve`s success lies its combination of precision mechanics, electro-technology and the consistent application of piezotechnology advantages. Despite their ultra-low power consumption, HOERBIGER piezo valves are well-suited for demanding applications in the process and automation industry that require broad ranges for flow, temperature and pressure control. High dynamics, German-engineered precision, non-self-heating operation and non-magnetic characteristics make the HOERBIGER piezo the valve of choice for the most demanding switching and control applications. Piezotechnology This strawberry contains approx. 130 joules of energy - sufficient to switch a piezo-valve more than 1 billion times. This makes HOERBIGER piezo pneumatics the ideal solution for environments with minimal energy reserves. High durability, reliability and dynamics Extremely low electric power consumption Key technology for intrinsically safe applications in hazardous areas Efficient to integrate ready-to-install module lowers development costs Digital positioner module All pneumatic functions integrated in a compact unit Modules for single- and doubleacting actuators Simple design, robust and reliable 2/2-way poppet valve Leakage-free High durability Short response times for high control performance Up to 50% lower manufacturing costs Pneumatic interface Flange-mountable for fast installation Dirt screen at the inlet for reliable operation even with poorly conditioned air Electrical interface Connector plug for fast connection to electronics Piezo pilot valves Fulfill requirements for intrinsically safe component Create reserves for additional diagnostic functions Very low air consumption

3 Increased efficiency for Smart Positioners Efficient in electrical power consumption extremely low energy consumption generates reserves for diagnostic functions Efficient in energy consumption unbeatably low air consumption saves operational costs Modern automation requires an increasing number of diagnostic functions in smart positioners. The electrical power consumption is critical, especially for EX-i (intrinsically safe) applications, because it is strong limited. The piezo valve technology developed by HOERBIGER offers the advantage of requiring electrical energy only needed during the short transitions switch-over processes (while solenoid systems require energy during the entire activation period). This unmatched low energy consumption gives positioner manufacturers the option to implement additional distinguishing features. The energy-efficient operation of process and chemical plants is increasingly becoming the operators center of attention. As much as half of the required compressed air can be achieved by a lower internal air consumption of the positioners used. The piezo-pneumatic pilot valves of the HOERBIGER positioner modules offer low air consumption of < 0.4 l/min (0.024 m³/h), regardless of operating pressure. Up to 50% lower costs for compressed air Up to 90% more energy reserve, e.g. for diagnostics Energy consumption Piezo Solenoid 0 energy reserve t HOERBIGER t comparable system to Actuator (valve movement) Positioner (air consumption) Annual costs for compressed air in a plant containing 500 systems each consisting of a 4 kn control valve actuator with one operation per minute and costs for compressed air of 1.3 ct/m³
