Rexroth DBETX-10/180G24-8NZ4M Direct-Acting Proportional Relief Valve
Part Number: 0811402017, Original Import from Germany
✅ Basic Information
Type: Direct-acting electro-hydraulic proportional relief valve (DBETX series, no built-in amplifier board, requires external proportional amplifier drive)
– Model Explanation:
– DBETX: Direct-acting proportional relief valve series
– 10: Series version (1X)
– 180: Maximum set pressure 180 bar
– G24: Electromagnet power supply DC24V
– 8NZ4M: Electrical plug specification, seal, and mounting type code
– Installation Standard: ISO 4401-03 (nominal diameter 6, base plate mounting)
📌 Core Technical Parameters
1. Maximum set pressure: 180 bar
2. Maximum pressure withstand of P port: 315 bar
3. Rated flow rate: 1 L/min (Maximum 1.5 L/min, a small flow valve, mostly used for pilot pressure control)
4. Power Supply: DC24V, proportional electromagnet
5. Weight: Approx. 2kg
6. Seal: Standard NBR rubber, optional fluororubber
🛠️ Applications
– Continuous, stepless electrical signal regulation of hydraulic system pressure, used for closed-loop pressure control
– Typical scenarios: Injection molding machines, die-casting machines, hydraulic testing machines, servo hydraulic stations, pilot pressure control in material testing equipment
>
> ⚠️ Note: DBETX does not have a built-in amplifier board; an external proportional amplifier must be connected, with an input ±10V or 4-20mA command signal to achieve linear pressure adjustment according to the electrical signal.
🔍 Differences within the same series
– DBETX: No integrated electronic board (your model), external amplifier required
– DBETE: Built-in integrated amplifier board, directly connects to control signal, simpler wiring
