DBETE-52/350G24K31A1V The Rexroth DBETE series proportional relief valve is originally manufactured in Germany

The set pressure stage is 350 bar, and the maximum operating pressure is also 350 bar. This is the highest pressure rating available in this series, allowing for precise pressure control up to this limit.

At the 350 bar pressure stage, the maximum flow rate is 2 L/min. This flow capacity is specified for the rated pressure and may vary with system conditions. Note that higher pressure stages typically have reduced flow rates compared to lower pressure models.

The "A1" designation refers to FPM (Fluoroelastomer) seals, which is essentially equivalent to FKM material. This designation may indicate a specific material grade, certification, or manufacturer's internal classification. These seals provide chemical resistance for aggressive media applications.

Both "A1" and "F1" typically refer to FKM/FPM fluoroelastomer materials with similar chemical resistance properties. The difference is primarily in the manufacturer's designation system or specific material certification standards. In practical terms, both are suitable for phosphate ester fluids and aggressive media, but always verify with the manufacturer's compatibility guide.

The "V" suffix may indicate special options, variants, or specific production features. This could include special testing requirements, documentation packages, delivery conditions, or other non-standard features. The exact meaning of "V" should be confirmed with the manufacturer's product documentation or technical support.

The FPM (A1) seals are designed for use with phosphate ester fluids and other chemically aggressive hydraulic media. This makes the valve suitable for fire-resistant fluid systems and applications where standard mineral oils cannot be used. Always verify fluid compatibility with the manufacturer's specifications.

The valve requires an external amplifier (such as VT5003, VT-VRPD-1, or compatible models) to provide the control signal and process position feedback from the integrated sensor. The amplifier must be compatible with 24 VDC power supply and the K31 electrical interface.
