The Sun Hydraulics DAAPECV (DAAPECV) is a pneumatically operated, spring-return cartridge valve, available in both normally open and normally closed configurations. Designed specifically for pilot flow applications, this model integrates seamlessly with Sun's pilot-operated, mainstage valves using the T8A cavity. This design choice simplifies installation by allowing both the control and primary function to share a single cavity, eliminating the need for separate pilot lines. The DAAPECV features hardened spool and sleeve components that ensure consistent operation, low spool leakage rates, and enhanced wear characteristics. It supports a maximum operating pressure of 5000 psi (350 bar), except for the pilot port which can handle up to 500 psi (35 bar). The preferred flow path is from port 2 to port 1, and it offers various pilot control port options which can be tailored according to specific requirements. For operation, the valve requires a minimum pilot pressure calculated by adding 20 psi to the pressure at Port 1 divided by 100, resulting in a functional range of 20 to 70 psi. In metric terms, this translates to adding 1.4 bar to the pressure at Port 1 divided by 100, equating to a pilot pressure range of approximately 1.4 to 5 bar. Additionally, this valve incorporates Sun's floating style construction which minimizes potential internal binding due to excessive installation torque or discrepancies in cavity/cartridge machining. With its compact design featuring a .25 gpm (1 L/min) capacity and minimal leakage at high pressures (10 drops/min at 5000 psi), the DAAPECV proves ideal for sophisticated hydraulic systems requiring reliable directional control in conjunction with high-performance main stage valves.

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.
