The Sun Hydraulics DNCATLN548 (DNCATLN548) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This valve is engineered with a closed transition between positions, significantly minimizing oil loss during shifting\u2014a crucial feature for pilot control circuits. Designed with port 3 as the inlet and port 1 as the tank, it offers optimal performance in this configuration; reverse flow is possible but not recommended due to potential performance degradation. The solenoid tube assembly of this valve is fatigue-rated for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Notably, this valve operates without requiring minimum hydraulic pressure and incorporates a wet armature design that allows the working fluid to surround the armature. The DNCATLN548 supports a range of coil termination and voltage options, some with surge protection features. Its high-efficiency solenoid provides robust spool actuating force per watt expended, promoting reliable valve shifting. The 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. This model uses Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. Additional specifications include a cavity type T-31A, series 1 capacity of 8 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at specified conditions of 10 in\u00b3/min (160 cc/min). The manual override requires a force of approximately 5 lbs at specific pressures and has an override stroke length of .10 inches (2.5 mm). The valve's hex size measures .78 inches (22.2 mm), with an installation torque range between 30-35 lbf\u00b7ft (41-47 Nm).

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.
