PILOT OPERATED PRESSUREVALVES IN CLOSED LOOP WITH PROPORTIONAL CONTROL AND INTEGRATED ELECTRONICS
PRE*J valves are pilot operated pressure relief proportional valves with integrated electronics and mounting interface in compliance with ISO 6264 standards (CETOP RP 121H).
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.
The monitoring of the value detected by the pressure transmitter is available on pin F.
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. In the event of special applications, you can customize the settings using the optional kit.
