The PRE*G* valves are proportional pressure relief valves, pilot operated, with integrated electronics and mounting interface in compliance with ISO 6264 standards.
These valves are 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.
Valves are available with different types of electronics, with analogue or fieldbus interfaces.
They are available in three sizes with flow rates up to 500 l/min and in four pressure control ranges up to 350 bar.
The valves are easy to install. The driver directly manages digital settings.
