The Sun Hydraulics DNCALCN914N (DNCALCN914N) is a high-performance, solenoid-operated directional valve, designed for robust and efficient hydraulic control in various applications. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with closed transitions that significantly minimize oil loss during shifting. This characteristic is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. With a design that allows port 3 to serve as the inlet and port 1 as the tank, the DNCALCN914N ensures reliable operation even though reverse flow capabilities are present but not recommended for optimal performance. The unit's solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), highlighting its suitability for high-pressure applications. Furthermore, the valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. This model incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. The wet armature design of the DNCALCN914N means that the working fluid surrounds the armature which could be a consideration if the coil remains energized over extended periods, especially with certain fluid types like water-glycol mixtures. Sun Hydraulics has equipped this model with various coil termination and voltage options, including designs with surge protection. Coil connectors compatible up to IP69K standards are available, ensuring durability and resistance against environmental factors. Additionally, this valve benefits from Sun's floating style construction which minimizes internal binding caused by excessive installation torque or machining variations in cavity-cartridge setups. Overall, the Sun Hydraulics DNCALCN914N offers robust construction and versatile performance characteristics suitable for demanding hydraulic applications requiring precise fluid control and reliability under pressure.

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.
