Product Description

Rexroth R901170278 DBET-62/200G24-8K4V

The Rexroth R901170278 DBET-62/200G24-8K4V is a pilot-operated proportional pressure relief valve. It is engineered to limit the pressure within a hydraulic system by means of a proportional solenoid, allowing for continuous and dynamic adjustment of the system pressure based on the electrical input signal. This valve, part of the DBET series, is recognized for its reliable performance and precision, making it suitable for applications that demand accurate pressure control. The “-62” designates a specific version within its series, “/200” indicates a maximum pressure setting of 200 bar, “G24” specifies a 24V DC solenoid, and “8K4V” refers to the electrical connection type, which typically includes features such as an LED and varistor.
