Product Overview
The HYDAC DB4E-012-100V is a direct-operated pressure relief valve engineered for precise system pressure limitation and overload protection in industrial hydraulic circuits. Manufactured by HYDAC, a globally recognized authority in fluid power and hydraulic filtration technology, this valve operates on a spring-loaded poppet principle: when system pressure exceeds the set value, the poppet lifts off its seat and diverts excess flow to the tank port, thereby maintaining the circuit at a stable, predetermined pressure level. With a nominal pressure setting of 100 bar and a size 012 (NG6 / CETOP 3) interface, the DB4E-012-100V serves as a critical safety and pressure-regulating component in manifold-mounted and inline hydraulic power units, test stands, and industrial machinery requiring dependable pressure control.
