The PRE10, PRE25 and PRE32 are proportional pressure relief valves, pilot operated, for subplate mounting. They are used to modulate the pressure of the hydraulic circuit and allow the use of the entire flow of the pump, even with pressure values near the set value.
They have a mechanical pressure limitation feature inside the pilot stage, for higher safety of the application. They are fitted with a pressure relief valve. The calibration is performed within the Duplomatic Company at the value of ≥ 15% of the maximum pressure value in the adjustment range. They are available in three sizes for flow rates up to 500 l/min and in five pressure regulation ranges up to 350 bar.
The valves can be controlled directly by a current-controlled power supply, or by an electronic card, to be order separately.
