The Sun Hydraulics DNCADWN612N (DNCADWN612N) is a high-performance, solenoid-operated directional valve characterized by its 4-way, 2-position configuration with a direct-acting, balanced spool design. This valve is particularly noted for its closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial feature in pilot control circuits. With a capacity of 8 gpm/30 L/min and an impressive maximum operating pressure of 5000 psi/350 bar, this valve is designed to handle demanding hydraulic applications efficiently. The DNCADWN612N operates without requiring a minimum hydraulic pressure and features EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids to avoid damage. The wet armature design of the valve ensures that the working fluid surrounds the armature, which can be vital in scenarios where the coil remains energized over extended periods. This model also boasts a variety of coil termination and voltage options to cater to diverse operational needs and environments. Further enhancing its utility are interchangeable coils compatible with other Sun Series 1 solenoid products, allowing for flexible installations and replacements. The valve also incorporates Sun's floating style construction which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This model responds typically within 50 ms and can handle up to 15,000 switching cycles per hour, making it both fast and durable for continuous use applications. Its robust manual override features require minimal force, ensuring easy operation under various pressure conditions.

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.
