Product Overview
Railway Parts Track Parts Hydraulic Valve For Plasser And Harsco Tamper
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. Our Products are widely used in Plasser major series of models.
FEATURES AT A GLANCE
Design features
1. Dry Electric Torque Motor – eliminates pick-up of magnetic particles from the fluid.
