How it Works The actuating element in the tecno valve is not a solenoid system, as in conventional proportional pressure regulating valves, but a piezo valve an encapsulated Piezo-ceramic element based on the jet-and- baffle principle. The piezo valve makes use of the Piezo effect: the Piezo-ceramic element bends when a voltage is applied to it. A built-in electronic control system applies variable voltage to the element, producing variable bending and therefore variable pressure on the diaphragm in the pilot chamber. Diaphragm movement is transferred to the main valve by a plunger acting against a spring. The pressure thus produced at the valve outlet is compared via a sensor with the preset value and if necessary corrected by the electronic control system. ersion , 8 8 ersion 0-0 0, 0 ersion , 0 0.

5 Sensitivity The smallest change in the electronic input signal which leads to a change in actual output pressure is referred to as sensitivity.this is expressed as a percentage of maximum output pressure. For the Tecno this value is < 0.% to < 0.5% depending on the version. Linearity The ideal curve showing output pressure in relation to electronic signal would be a straight line. Linearity is the maximum deviation from the straight line, expressed as a percentage of maximum output pressure. X p F= p (%) X Hysteresis The same electronic signal generates slightly different actual output pressures, depending on whether the previous signal was higher or lower. This difference, known as hysteresis, is caused by friction and temporary deformation of elastic components. The hysteresis of the electronically operated pressure regulating valve AIRFIT tecno from HOERBIGER is between < 0. % and < 0.5 % of the output pressure. Repeatability Control components, for a given set value, usually produce repeated actual values which differ less from each other than from the absolute set value, because the relatively large linearity deviation is excluded.

11 Sensitivity The smallest deviation from set output pressure which leads to a change in actual output pressure is referred to as sensitivity and this is expressed as a percentage of maximum output pressure. Sensitivity of the XRE II valve is below 0.5%, which allows output pressure to be set very precisely. X p X Linearity The ideal curve showing output pressure in relation to electronic signal would be a straight (linear) line (see dotted line), to predict exactly which pressure can be expected at a given voltage. The deviation can be calculated from the maximal deviation from the straight line, in relation to the highest possible pressure. F= p (%) Hysteresis The same set output pressure generates slightly different actual output pressures, depending on whether the previous setting was higher or lower. This difference, known as hysteresis, is caused by friction and temporary deformation of elastic components. The hysteresis of the SRE valve is below 0.. F= p (%) Repeatability Control components, for a given set value, usually produce repeated actual values which differ less from each other than from the abolute set value, because the relatively large linearity deviation is excluded. Repeatability is improved if hysteresis is minimised. Data Sheet E-
