The Sun Hydraulics DAAPFHN (DAAPFHN) is a high-performance, pneumatically operated, spring-return cartridge valve. Designed for precision in pilot flow applications, this model features a 2-position, 2-way directional control setup and is available in both normally open or normally closed configurations, catering to diverse operational requirements. Its integration with Sun\u2019s T8A cavity allows for seamless use with Sun\u2019s pilot-operated, mainstage valves enhancing system efficiency by eliminating the need for separate pilot lines and reducing the complexity of system design. This valve supports a preferred flow path from port 2 to port 1 and offers various pilot control port options to suit different system needs. The DAAPFHN boasts a robust construction with a hardened spool and sleeve that ensure consistent operation, low spool leakage rates, and superior wear characteristics. It operates within a pilot pressure range of 20 to 70 psi or 1.4 to 5 bar, calculated through a specific formula relating port pressure to required pilot pressure. The maximum operating pressure for this valve stands at an impressive 5000 psi (350 bar), while the maximum valve leakage at this pressure is restricted to 10 drops per minute. Installation requires adherence to specified torque values to prevent internal part binding due to excessive torque or machining variations in the cavity/cartridge assembly. This model uses Viton seals for enhanced performance under various conditions and accommodates installation torque between 20 - 25 lbf ft (27 - 33 Nm). With its compact design featuring a hex size of 7/8 inches (22.2 mm) and flow capacity of .25 gpm (1 L/min), the DAAPFHN is an exemplary choice for systems requiring reliable and efficient directional control in hydraulic applications.

These pilot-stage, directional, 2-position, 2-way valves are pneumatically operated, spring-return cartridges and are available in either normally open or normally closed configurations. 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.
- 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 = 20 psi + pressure @ Port 1 divided by 100. This results in a pilot pressure range of 20 to 70 psi. In metric; pilot pressure = 1,4 bar + pressure @ Port 1 divided by 100. This results in a pilot pressure of 1,4 to 5 bar.
- All ports will accept 5000 psi (350 bar) with the exception of the pilot port which accepts 500 psi (35 bar) max.
- 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.
