The Sun Hydraulics DNCATLN848 (DNCATLN848) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve features a closed transition between positions to minimize oil loss during shifting, which is particularly beneficial for pilot control circuits. It operates with a maximum capacity of 8 gpm (30 L/min) and can handle pressures up to 5000 psi (350 bar), making it suitable for demanding applications. The valve's design allows for direct actuation without the need for minimum hydraulic pressure, and its solenoid tube assembly is fatigue-rated for high-pressure service. The DNCATLN848 incorporates a wet armature design where the working fluid surrounds the armature, providing exposure to coil-generated heat. Users should be aware that certain fluids, like water-glycol mixtures, may degrade over time at these temperatures. This valve offers flexibility with various coil termination and voltage options, including configurations with surge protection. The solenoid's magnetic design ensures high efficiency and reliable shifting by maximizing spool actuating force per watt consumed. The product features Sun's floating style construction to reduce internal part binding due to excessive installation torque or machining variations. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For enhanced environmental protection, additional weatherized coils and kits are available with connector options rated up to IP69K. Installation requires a torque of 30-35 lbf ft (41-47 Nm), and the valve has a hex size of 7/8 in (22.2 mm). It has a typical response time of 50 ms and supports a switching frequency of up to 15000 cycles per hour. The DNCATLN848 comes equipped with Viton seal kits for both cartridge and coil applications, ensuring compatibility with specific fluid types while maintaining robust operation standards.

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.
