The Sun Hydraulics DBAHAHN (DBAHAHN) is a high-performance hydraulic valve designed for precise pilot flow control in various applications. This model, part of the P series and housed within a T9A cavity, features a directional, 2-position, 3-way configuration with options for normally open connections from port 1 to ports 2 or 3. It operates as a hydraulically operated, spring-return cartridge valve which can handle maximum operating pressures up to 5000 psi (350 bar) across all ports including the pilot control port. The DBAHAHN valve is engineered with hardened spool and sleeve for enhanced durability and consistent performance, ensuring low spool leakage rates and superior wear characteristics. It requires a minimum pilot pressure calculated by the formula: pilot pressure = 85 psi + pressure at Port 1 x .023 (or in metric terms, 6 bar + pressure at Port 1 x 0.023), translating to a pilot pressure range of approximately 85 to 200 psi (6 to 14 bar). This makes it adaptable for varying operational demands. Furthermore, the valve incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. The design supports an optimal flow capacity of .25 gpm (1 L/min) and features robust sealing with Viton material for reliable operation under diverse conditions. With a hex size of 7/8 inch (22.2 mm) and an installation torque requirement between 20 - 25 lbf ft (27 -33 Nm), the DBAHAHN ensures ease of installation and maintenance while providing effective control in hydraulic systems.
