RODUCT FEATURES & BENEFITS
VPS021 is a stackable, load sensing, pre-compensated proportional valve provides flow control independent of load pressure from 5 to 130lpm.
PRECISE CONTROL & EFFICIENCY
VPS021 offers precise control and efficiency for a wide range of applications from mobile cranes, fire engines, agricultural machineries, aerial platforms & lifts, concrete pumps to mining and drilling machines. Energy saving load sensing technology increase efficiency.
TIME SAVING MODULAR STRUCTURE
Modular structure enables unlimited configurations to the user with less effort.
ADVANCED CUSTOMIZED CONTROL
Thanks to the careful design engineering, VPS021 offers advanced customized control with shock valves, LSA/LSB pressure relief valves, spool stoke limiters, precise spool adjustents specific for the application requirements. The valve combines advanced abilities through various actutator options: manual, hydraulic, proportional, PWM, Voltage and CANBus proportional control for open and closed loop systems.
With pressure compensators in each section, actuators are compensated and maintained a constant pressure drop against changes in load.
