The Sun Hydraulics DNCADAV (DNCADAV) is a solenoid-operated, 4-way, 2-position cartridge valve, characterized by its direct-acting, balanced spool design. This valve ensures smooth transition between positions with a closed transition feature that significantly minimizes oil loss during shifting\u2014a crucial aspect in pilot control circuits. The valve operates optimally with port 3 as the inlet and port 1 as the tank outlet, although it allows for reverse flow under specific conditions. This model is particularly robust with a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar) service. It does not require any minimum hydraulic pressure to function due to its direct actuation mechanism. The DNCADAV is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based substances. A notable feature of this valve is its wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to prolonged heat from an energized coil. The DNCADAV offers various coil termination and voltage options including models with surge protection and coils rated up to IP69K for enhanced environmental protection. Additionally, the valve incorporates Sun's floating style construction which helps prevent internal parts binding that can occur due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 8 gpm (30 L/min), the DNCADAV provides reliable performance and versatility in application. Its quick response time (typical at 50 ms) and high switching frequency (up to 15000 cycles/hr) make it suitable for demanding operational environments requiring precise control and durability.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- 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.
