The Sun Hydraulics DRBDLAN is a high-performance, pilot-operated pressure reducing/relieving valve. This cartridge-style valve is designed to accurately regulate pressure in a secondary hydraulic circuit, independent of variations in the main circuit’s pressure. It functions by diverting main circuit flow to the tank when the secondary pressure exceeds the valve’s setting. Furthermore, its integral relieving feature protects the secondary circuit from overpressure events caused by external forces or thermal expansion. The DRBDLAN is engineered for durability and precision, fitting into a standard T-11A cavity, making it a reliable choice for a wide range of industrial and mobile hydraulic applications.
