Web Aligner System is much more than just an energy source. It’s designed for accurate and high quality edge guiding system. However, because it normally furnishes modulated power to the actuating devices. It’s amplifier of control signals, also power source In addition to providing hydraulic power for the actuating circuit the power unit produces pneumatic power for the sensors. High quality sensor supply pressure must remain constant, and the power supply provides this element. Water, oil and scale contamination and other miscellaneous plant air problems are also avoided.
