Rexroth DBETX-10/180G24-8NZ4M Proportional Pressure Relief Valve 0811402017
Rexroth DBETX-10/180G24-8NZ4M (part number 0811402017), a German-made direct-acting proportional relief valve, does not have a built-in amplifier board and requires an external proportional amplifier for drive.
Driven by a DC24V proportional solenoid, it has a maximum pressure adjustment of 180 bar and is suitable for small flow rates. It allows for continuous stepless adjustment of hydraulic pressure based on an electrical signal and is primarily used for pilot pressure control. It is widely used in injection molding machines, hydraulic testing machines, and servo hydraulic systems to achieve precise closed-loop pressure control.
