Atos North America Proportional Electrohydraulic Controls for PVPC Pumps PVPC Controls

The variable displacement axial piston pumps type PVPC, can be supplied with advanced electrohydraulic proportional controls: open loop pressure control load sensing flow control open and closed loop P/Q controls They allow the performance of high dynamics and fine regulations, directly commanded from PLC or from the machine controller. They are available with separate driver or with integral electronics. New PES digital controllers, integrated to the pump, realize alternate closed loop controls of pressure, flow and max power limitation. The P/Q controls are also available with optional sequence modules that allow the pump to operate with minimum pressure in the circuit close to zero.
