VPS BREVINI is a leading company manufacturer of directional control valves, in two versions: monoblock and modular. Monoblock, up to 6 selections, with flow rates 35 and 60 l/min., modular with flow rates 35, 60, 100 and 200 l/min. All of them are a suitable range for 350 bar, and more, working pressure.
Brevini manufactures a selection of the latest generation of hydraulic proportional directional valves (HPV) that perform two simultaneous functions: directional control and flow control that is unaffected by load variations. By means of logical selection, a LS signal (feedback) is taken from the highest pressure ports and it's sent to the flow-pressure regulator in the inlet section (if the circuit operates with a fixed displacement pump) or directly to the Load Sensing pump (for a closed centre circuit). As long as the circuit senses the ^p, the valve will maintain its proportionality properties.
The main hydraulic features of the HPV valves are summarized below:
Flow control (metering) is independent from load, therefore the flow provided at the ports does not change with a variation in work pressure of the utilities they control.
The flow of each function is independent from the simultaneous work pressures, thus allowing simultaneous operations to be carried out without reciprocal effects.
Electrical unloading of the LsA and LsB signals on each element.
Excellent flow control characteristics, without dead bands.
Symmetrical distribution, that allows the position of the manual control to be reversed with all servocontrols.
Precise and safe remote controls (hydraulic, proportional electrohydraulic) that are easy to install.
Operation with both variable displacement pumps with a Load Sensing regulator and fixed displacement.
Remote control of operating pressure of each port.
