The Sun Hydraulics DAAHACV (DAAHACV) is a pilot-stage, directional, 2-position, 2-way valve designed for hydraulic operations with a spring-return mechanism. This model can be configured as either normally open or normally closed, making it versatile for various hydraulic control applications. It utilizes the Sun T8A 2-port cavity, which is specifically designed to work seamlessly with Sun's pilot-operated main stage valves, enhancing the system's efficiency by eliminating separate pilot lines and reducing the need for multiple cavity machining. The DAAHACV valve supports a maximum operating pressure of 5000 psi (350 bar) across all ports, including the pilot control port. It features a hardened spool and sleeve to ensure consistent operation, low leakage rates, and superior wear characteristics. The preferred flow path for this valve is from port 2 to port 1, and it offers different pilot control port options to suit various requirements. To operate effectively, the minimum pilot pressure needed is calculated based on the formula: pilot pressure = 85 psi + (pressure at Port 1 x .023), translating into a range of approximately 85 to 200 psi. In metric units, this formula adjusts to: pilot pressure = 6 bar + (pressure at Port 1 x 0.023), resulting in a range of about 6 to 14 bar. Additionally, this model incorporates Sun's floating style construction which minimizes potential internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. The valve dimensions include a hex size of 7/8 inches (22.2 mm) and an installation torque requirement ranging from 20 -25 lbf ft (27 -33 Nm). The cartridge also uses Viton seals for enhanced performance under various operational conditions.

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.
