The Sun Hydraulics DAAHBHV (DAAHBHV) is a versatile hydraulic control valve designed for pilot flow applications, featuring a 2-position, 2-way configuration. This model is engineered to be used in conjunction with Sun's pilot-operated, mainstage valves due to its compatibility with the Sun T8A cavity. The valve can function in either a normally open or normally closed configuration, providing flexibility depending on the required application. Key features of the DAAHBHV include hardened spool and sleeve for consistent operation and low leakage rates, ensuring superior durability and wear resistance. It supports a maximum operating pressure of 5000 psi (350 bar) across all ports, including the pilot control port. The preferred flow path for this valve is from port 2 to port 1, and it offers various pilot control port options which can be tailored according to specific requirements. This model incorporates Sun's floating style construction which minimizes internal parts binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. Installation involves first securing the main stage valve at the correct torque followed by inserting the T8A pilot control section into the main stage valve according to required torque specifications. The DAAHBHV operates within a pilot pressure range of 85 to 200 psi (6 to 14 bar), calculated by a specific formula relating pilot pressure with pressure at Port 1. It is also notable for its minimal hydraulic oil leakage rate at high viscosity, maintaining operational efficiency and reliability in various hydraulic systems.

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.
