Hydraulic Servo-valve EL-T76.00-MO-191C Series for Railway Industry Plasser
Products are widely used in Plasser major series of models.
This Series fills the gap between crude on/off controls and conventional high performance servovalves. This servovalve design offers true proportional servocontrol for a cost significantly below previous alternatives. The 62 Series has the same internal mechanical feedback used in higher performance servovalves. This feedback arrangement, together with the flexure tube dry motor, provides inherent reliability proven by years of successful experience. Motorcap can be turned by 180 degree.
FEATURES AT A GLANCE
Design Features:
》Dry Electric Torque Motor – eliminates pick-up of magnetic particles from the fluid.
》Frictionless double nozzle pilot stage with flexure tube 》Reliable mechanical feedback – eliminates levers, springs, pivots, and other complex mechanisms. 》Mechanical null adjustment – permits convenient set-up of system 》Integral filter screens - protect valve from inadvertent system contamination.
