The Sun Hydraulics DNCATCN914N (DNCATCN914N) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This valve is engineered with a closed transition between positions, which significantly minimizes oil loss during shifting\u2014an essential attribute for pilot control circuits. It is primarily configured with port 3 as the inlet and port 1 as the tank; while reverse flow is feasible, it may not perform optimally and is therefore not advised. The solenoid tube assembly of this valve is fatigue-rated for service up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. Notably, this valve operates without requiring any minimum hydraulic pressure due to its direct actuation design. The valve employs a wet armature design where the working fluid envelops the armature, exposing it to coil-generated heat\u2014a consideration when using fluids like water-glycol mixtures that could degrade over time at elevated temperatures. The DNCATCN914N offers various coil termination and voltage options, including those with surge protection, making it adaptable to different system requirements. Its high-efficiency solenoid delivers substantial spool actuating force per watt expended, ensuring reliable operation. Additionally, the interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. For environmental resilience, coil connector options are available with ratings up to IP69K. The valve incorporates Sun's floating style construction to reduce the risk of internal component binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. With a capacity of 8 gpm (30 L/min) and maximum leakage specifications at 10 in/min at 3000 psi (160 cc/min at 210 bar), this cartridge valve is designed for high-frequency switching operations up to 15,000 cycles per hour.

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.
