Slide 6: VPL Design Benefits - Pressure Feedback Pulsar Solenoid
VPL Design Benefits - Pressure Feedback Pulsar Solenoid Provides precise control with reduced operator fatigue caused by over controlling the machine • Pressure Feedback Solenoids reduce static friction resulting in superior control with very low hysteresis • Patented Dual Control Input • Current Co
Slide 7: VPL Design Benefits – Individual Pressure Compensation
VPL Design Benefits – Individual Pressure Compensation Provides outstanding control while multi-functioning your machine resulting in less operator input • Individual Pressure Compensation in each function will maintain constant speeds regardless of different load conditions that are being seen in t
Slide 8: VPL Design Benefits – Pressure Limiters
VPL Design Benefits – Pressure Limiters Reduce Operating Cost by providing an energy efficient System • Pressure Limiters can be incorporated into the section to limit maximum pressure to a lower setting than the main system pressure. • This device pilot operates the Individual Pressure Compensator
Slide 9: VPL Design Benefits – Adjustable Pressure Compensator
VPL Design Benefits – Adjustable Pressure Compensator Maximize proportional control to the actuator by providing precise flow from the valve • Adjustable Pressure Compensator regulates the pressure drop across the main spool to provide exact flow needed to maintain full spool travel. • Competitors a
