Pilot-operated relief valve PRE* series
برند:
Duplomatic Oleodinamica
مشخصات:
— PRE* valves are pilot operated pressure relief valves with
electric proportional control 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.
— Pressure can be modulated continuously in proportion to
the current supplied to the solenoid.
— These valves can be controlled directly by a current control
supply unit or by means of the relevant electronic control
units to exploit valve performance to the full (see par. 10).
— They are fitted with a manual pressure relief valve which is
factory set to ≥15% of the maximum value in the pressure
control range.
— They are available in three sizes for
flow rates up to 500 l/min and in four
pressure control ranges up to 350 bar.
