The Sun Hydraulics DAAHAHN (DAAHAHN) is a pilot-stage, directional, 2-position, 2-way valve designed for hydraulic operations with a spring-return mechanism. These cartridges are specifically made for pilot flow applications and are compatible with Sun's T8A cavity. This compatibility allows them to be used effectively alongside Sun's pilot-operated, mainstage valves, ensuring streamlined integration and functionality in hydraulic systems. The DAAHAHN model can function in either a normally open or normally closed configuration based on the system's requirements. This valve utilizes the T8A 2-port cavity, which simplifies installation by eliminating separate pilot lines and requiring only one cavity to be machined for both control and primary functions. It is designed to ensure that the preferred flow path is from port 2 to port 1, with various pilot control port options available depending on specific system needs. The valve can withstand a maximum operating pressure of 5000 psi (350 bar) across all ports including the pilot control port. Constructed with a hardened spool and sleeve, the DAAHAHN ensures consistent operation, low spool leakage rates, and superior wear characteristics. It requires a minimum pilot pressure determined by an established formula which results in a required range of 85 to 200 psi or equivalent in metric units as 6 to 14 bar. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. For maintenance and replacements, it supports Viton seal kits specified under part number: 990508006. The valve also has specific installation torque requirements set between 20 \u2013 25 lbf ft (27 \u2013 33 Nm) and features a hex size of 7/8 inch (22.2 mm). This makes the DAAHAHN model an adaptable solution for various hydraulic circuit applications requiring precise control through pilot-stage operation.

These pilot-stage, directional, 2-position, 2-way valves are hydraulically operated, spring-return cartridges and are available in either a normally open or normally closed configuration. These cartridges are designed for pilot flow applications and utilize Sun's T-8A cavity so they can be used in conjunction with Sun's pilot-operated, main-stage valves.
- Utilizes the Sun T-8A 2-port cavity making it the ideal choice to use in conjunction with Sun's main stage pilot or vent-to-operate cartridges. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function. Note: All 2-position, 2-way pilot stage control cartridges utilize the same cavity and are physically interchangeable. Functionality is the only consideration.
- Note: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
- The preferred flow path through the valve is port 2 to port 1.
- 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.
