The Sun Hydraulics DBAHDHN (DBAHDHN) is a pilot-stage, directional, 2-position, 3-way hydraulic valve designed for efficient control in various hydraulic systems. It operates as a spring-return cartridge and comes in two spool configurations: normally open from port 1 to port 2 and normally open from port 1 to port 3, catering to different circuit requirements. This valve is particularly suited for pilot flow applications, offering versatility through various pilot control port options. Constructed with a hardened spool and sleeve, the DBAHDHN ensures consistent operation with low spool leakage rates and superior wear characteristics, making it reliable for demanding applications. It supports a maximum operating pressure of 5000 psi (350 bar) across all ports including the pilot control port. The minimum pilot pressure required for operation ranges from 85 to 200 psi or 6 to 14 bar, calculated based on the pressure at Port 1. This model incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue stemming from excessive installation torque or variations in cavity/cartridge machining. The valve has a maximum flow capacity of .25 gpm (1 L/min) and exhibits maximum leakage at full pressure of about ten drops per minute at an oil viscosity of 110 SUS (24 cSt). For installation, the valve hex size is .875 inches (22.2 mm), with an installation torque range of between 20-25 lbf.ft (27-33 Nm). Additionally, it uses Viton seals for enhanced performance under varying conditions. The Sun Hydraulics DBAHDHN is an optimal choice for system designers looking for a robust and flexible solution in hydraulic system control, ensuring high performance and reliability across a broad range of industrial applications.

These pilot-stage, directional, 2-position, 3-way valves are hydraulically operated, spring-return cartridges and are available in two spool configurations; normally open 1 to 2 and normally open 1 to 3. These cartridges are designed for pilot flow applications.
- Different pilot control port options are available. See Option Selection for details.
- All ports will accept 5000 psi (350 bar) including the pilot control port.
- Hardened spool and sleeve provide consistent operation, low spool leakage rates and superior wear characteristics.
- The minimum pilot pressure required to operate the valve is determined by the following formula: pilot pressure = 85 psi + pressure @ Port 1 times .023. This results in a pilot pressure range of 85 to 200 psi. In metric; pilot pressure = 6 bar + pressure @ Port 1 times 0,023. This results in a pilot pressure of 6 to 14 bar.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
