The Sun Hydraulics DBAHDHV (DBAHDHV) is a highly specialized hydraulic valve designed for precision in pilot flow applications. This directional, 2-position, 3-way valve operates as a hydraulically operated, spring-return cartridge and is available in two spool configurations: normally open from port 1 to port 2 and normally open from port 1 to port 3. Engineered for durability and reliable performance, the DBAHDHV features hardened spools and sleeves that ensure low leakage rates and superior wear characteristics even under rigorous conditions. With a maximum operating pressure of 5000 psi (350 bar) across all ports including the pilot control port, this valve is suited for high-pressure environments. The minimum pilot pressure required to operate the valve ranges from 85 to 200 psi (6 to 14 bar), calculated based on the pressure at Port 1. This flexibility allows it to be used in various hydraulic systems without the risk of internal parts binding, thanks to Sun\u2019s floating style construction which compensates for installation torque and machining variations. The DBAHDHV fits into a T9A cavity and belongs to the P series with a flow capacity of .25 gpm (1 L/min). It exhibits maximum leakage at full pressure of about 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). For installation, a hex size of 7/8 in. (22.2 mm) is required with an installation torque between 20 -25 lbf ft (27 -33 Nm). The valve also supports Viton seals through kit number: 990509006, ensuring robust performance against various fluids and temperatures within hydraulic systems.
