The Sun Hydraulics DNCATLN824 (DNCATLN824) 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, significantly reducing oil loss during shifting, which is particularly beneficial in pilot control circuits. It is optimized for systems using port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly of this valve is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. This model does not require a minimum hydraulic pressure for operation due to its direct actuation design. The DNCATLN824 employs a wet armature design that immerses the armature in working fluid, which can influence thermal management if the coil remains energized over extended periods. Notably, fluids like water-glycol mixtures may degrade under such conditions. A range of coil termination and voltage options are available to suit different applications, with some options providing surge protection and environmental ratings up to IP69K for enhanced durability against harsh environments. This valve incorporates Sun's floating style construction to minimize internal component binding due to installation torque or machining variations in the cavity/cartridge interface. The model supports various interchangeable coils from Sun's Series 1 solenoid products that can be mounted bidirectionally on the tube. With an operational capacity of 8 gpm (30 L/min) and a typical response time of 50 ms, the DNCATLN824 offers efficient performance with maximum leakage at specified conditions limited to 10 in\u00b3/min (160 cc/min). Additionally, manual override capabilities are included with specific force requirements and stroke dimensions provided for precise manual operation when necessary.

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.
