The Sun Hydraulics DAAHDCV (DAAHDCV) is a pilot-stage, directional, 2-position, 2-way hydraulic valve designed for precise control in hydraulic systems. This valve features a spring-return mechanism and is available in both normally open or normally closed configurations, catering to diverse operational requirements. It is specifically engineered to fit the Sun T8A cavity, ensuring compatibility with Sun's pilot-operated mainstage valves which simplifies system design by reducing the need for separate pilot lines and minimizing the number of cavities that need to be machined. The DAAHDCV valve supports a maximum operating pressure of 5000 psi (350 bar) across all ports, including the pilot control port. It offers a flow capacity of approximately 0.25 gpm (1 L/min) and maintains tight control over leakage with a maximum rate of 5 drops per minute at 110 SUS (24 cSt). Installation requires precise torque values, with the main stage valve needing installation first followed by the T8A pilot control section. This valve utilizes hardened spool and sleeve components to deliver consistent operation, low leakage rates, and superior wear characteristics. The minimum pilot pressure required to operate this valve ranges from 85 to 200 psi or equivalently from 6 to 14 bar based on a specific calculation formula provided by Sun Hydraulics. Additionally, this product incorporates Sun's floating style construction which aids in reducing internal part binding due to excessive installation torque or variations in cavity/cartridge machining. With different pilot control port options available for selection based on system requirements, this versatile component ensures efficient functionality tailored for various hydraulic applications. The design also emphasizes ease of maintenance and robust performance in demanding environments.

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.
