The Sun Hydraulics DAAHBCV (DAAHBCV) is a highly versatile and robust hydraulic control cartridge designed for pilot flow applications. This 2-position, 2-way valve is available in both normally open and normally closed configurations, ensuring suitability for a variety of operational setups. It leverages the T8A cavity design, which is optimal for use with Sun's pilot-operated, mainstage valves, enhancing integration and simplifying system complexities. Specifically engineered to accommodate pilot stage control, the DAAHBCV features a maximum operating pressure of 5000 psi (350 bar) and can handle a flow capacity of up to .25 gpm (1 L/min). The valve's construction includes a hardened spool and sleeve which not only provide consistent operation but also boast low spool leakage rates and superior wear characteristics. This durability is crucial for maintaining performance in demanding environments. The installation process requires precise torque values; the main stage valve must be installed first at the correct torque followed by the T8A pilot control section into the main stage valve to its required torque value. The preferred flow path through the DAAHBCV is from port 2 to port 1, with all ports capable of accepting up to 5000 psi including the pilot control port. For ease of application adaptability, different pilot control port options are available which can be selected based on specific needs. The minimum pilot pressure necessary to operate this valve varies with pressure at Port 1, with a formula provided to calculate this threshold accurately. Additionally, Sun's floating style construction minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations, ensuring reliable operation under varied 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.
