The Sun Hydraulics DNCADCN548 (DNCADCN548) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with closed transition between positions. This design significantly reduces oil loss during shifting, making it particularly beneficial for pilot control circuits. The valve is configured to handle a flow capacity of 8 gpm/30 L/min with port 3 as the inlet and port 1 as the tank. It operates effectively under a maximum pressure of 5000 psi/350 bar and boasts a quick response time of approximately 50 ms. This model is engineered with a wet armature design, where the working fluid surrounds the armature which can be exposed to heat if the coil remains energized over extended periods. Such conditions may affect fluid integrity, particularly with water-glycol mixtures which can degrade and form varnishes impacting cartridge function. Users should note that while reverse flow through the valve is possible, optimal performance in this mode is not assured and generally not recommended. The DNCADCN548 valve supports various coil termination and voltage options, including configurations with surge protection. Its coils are compatible across other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The options for coil connectors are robust, offering ratings up to IP69K for enhanced environmental protection. Additional features include Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. The solenoid\u2019s unique magnetic design enhances efficiency by maximizing spool actuating force per watt expended, ensuring reliable valve operation even under demanding conditions. This model also allows for manual override with minimal force requirement and provides interchangeable seals for different fluid types to ensure operational integrity and longevity.

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.
