DBETR-1X/80G24K4M Rexroth proportional pressure limiting valve DBETR made in Germany

This is a direct-operated proportional relief valve. Its primary function is to continuously and precisely regulate hydraulic system pressure by receiving electrical control signals (typically 0-20mA or 0-10V), while also serving as a safety valve to prevent system overpressure. It's designed for remote electrical control of pressure in hydraulic systems.

The "80" specifies the maximum pressure setting capability of 80 bar. This is a mid-range pressure setting in the DBETR series. The valve can be electrically adjusted to regulate pressure from 0 to 80 bar, making it suitable for a wide range of industrial appliions.

• Operating voltage: 24V DC (±10%)
• Nominal current: Typically 0.8-1.0 A (varies by coil type)
• Coil resistance: Approximately 19-29 Ω (at 20°C)
• Electrical connection: DIN 43650 standard plug connector (K4 type)
• Requires compatible proportional amplifier
• Control signal: 0-10V or 4-20mA

The "K4" indies the electrical connection type. Specifically, it means the valve comes with a DIN 43650 standard plug connector (without mating connector) for the proportional solenoid. The "K" series typically refers to the connector configuration, with "K4" being a specific variant in this product family.

The key difference is the pressure setting range: this model has a 0-80 bar range, while the 30 bar version is limited to 0-30 bar. All other core parameters (size, voltage, current, port size, connector type) remain identical. The 80 bar version provides higher pressure capability for appliions requiring medium-pressure control.
