The Sun Hydraulics DNCADWN636 (DNCADWN636) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition shifting. This design minimizes oil loss during position changes, which is crucial in maintaining efficiency in pilot control circuits. The valve operates without the need for minimum hydraulic pressure and is rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. This model boasts a robust build with an EPDM seal configuration tailored for systems using phosphate ester fluids; however, it is vulnerable to damage if exposed to petroleum-based substances. Its wet armature design allows the working fluid to surround the armature, which can be beneficial or detrimental depending on the duration the coil remains energized and the type of fluid used. The DNCADWN636 offers flexibility with various coil termination and voltage options, including models with surge protection. Its coils are compatible with other Sun Series 1 solenoid products and can be installed in either orientation on the tube. Additionally, environmental protection is enhanced through available weatherized coils and kits. Sun Hydraulics has incorporated its floating style construction into this model to reduce internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The valve's specifications include an 8 gpm (30 L/min) capacity at maximum operating pressures of 5000 psi (350 bar), rapid response times typical at 50 ms, and a manual override feature requiring minimal force. It supports a switching frequency of up to 15,000 cycles per hour and maintains maximum valve leakage well within acceptable limits under operational pressures.

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.
