The Sun Hydraulics DAAHDHV (DAAHDHV) is a versatile hydraulic valve designed for precision in pilot flow applications. Featuring a 2-position, 2-way configuration, this valve can be set up as either normally open or normally closed based on the requirements of the system. It is specifically crafted to function within Sun's T8A cavity, which facilitates integration with Sun's pilot-operated mainstage valves, ensuring a streamlined setup without the need for separate pilot lines. The DAAHDHV valve supports a maximum operating pressure of 5000 psi (350 bar) across all ports, including the pilot control port. It is engineered with a hardened spool and sleeve to enhance durability and minimize leakage, which is critical for maintaining consistent operational standards. The minimum pilot pressure necessary for operation starts from 85 psi (approximately 6 bar), scaling up based on the pressure at Port 1. This model also incorporates Sun's floating style construction that reduces risks associated with internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature ensures more reliable performance and longevity of the valve system. For installation, it is recommended that the main stage valve be installed first to its correct torque value followed by the T8A pilot control section into the main stage valve at its required torque value. The preferred flow path through this model is from port 2 to port 1, and it offers different pilot control port options which can be selected based on specific application needs. Overall, the Sun Hydraulics DAAHDHV provides robust performance for hydraulic systems requiring precise control over pilot flows, making it an essential component in various hydraulic applications.

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.
