The Sun Hydraulics DNCATLN514 (DNCATLN514) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, which minimizes oil loss during shifting\u2014a critical factor in pilot control circuits. It operates with a valve capacity based on port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended for optimal performance. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring durability under high-pressure conditions. Notably, this valve does not require minimum hydraulic pressure for operation due to its direct actuation design. The DNCATLN514 incorporates EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. A wet armature design allows the working fluid to surround the armature and absorb heat from the coil, which could be significant if the coil remains energized for extended periods. This feature necessitates attention to fluid types used, as certain fluids like water-glycol mixtures may degrade over time due to heat exposure. A variety of coil termination and voltage options are available to accommodate different operational requirements, some offering surge protection and IP69K ratings for enhanced environmental resilience. The high-efficiency solenoid design provides substantial spool actuating force per watt expended, ensuring reliable valve operation. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The DNCATLN514 boasts a switching frequency of up to 15,000 cycles per hour and includes manual override capabilities requiring minimal force. Its construction employs Sun's floating style design to reduce risks of internal binding from installation torque or machining variations.

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.
