• Operating pressure of 350 bar maximum, NBR seals
• 6.3 kg mass, subplate mounting to ISO 6264-10-17

Technical data

Application

The valve protects circuits that move large oil volumes at low pressure, such as prefill and return stages of large presses. Its unloading function switches the circuit to zero pressure during pauses without stopping the pump.
