The PRE*G valves are pilot operated pressure relief proportional valves with integrated electric proportional control and mounting interface in compliance with ISO 6264 (CETOP RP 121H) standards.
These valves are normally used to control hydraulic circuit pressure and enable the use of the full flow rate of the pump, even with settings approaching calibrated values.
The two-stage design and wide passages ensure reduced pressure drops thereby improving the system energy performance.
They are fitted with a manual pressure relief valve which is factory set to ≥15% of the maximum value in the pressure control range.
The valves are available with command signal in voltage or current and on board electronics with internal enable, external enable or 0V monitor on pin C.
A solenoid current monitoring signal is available.
The valves are easy to install. The driver directly manages digital settings.
They are available in three sizes with flow rates up to 500 l/min and in four pressure control ranges up to 350 bar.
