The Sun Hydraulics DNCADCN948 (DNCADCN948) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that serves as a direct-acting, balanced spool directional valve. Ideal for applications requiring precise control and reliability, this model ensures minimal oil loss during position transitions due to its closed transition design. This feature is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. Engineered for versatility and durability, the DNCADCN948 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 8 gpm (30 L/min), based on port 3 being the inlet and port 1 as the tank. While reverse flow is possible with this valve, optimal performance following this setup is not guaranteed. The solenoid tube assembly of the valve is fatigue rated for high-pressure service, ensuring long-term reliability even under strenuous conditions. This model incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids which could cause damage. Additionally, the wet armature design of the DNCADCN948 means that the working fluid surrounds the armature; prolonged energization of the coil should be managed carefully to prevent fluid degradation. For further customization and application-specific adjustments, Sun Hydraulics offers a variety of coil termination options and voltage configurations with or without surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Environmental resilience can be enhanced through available weatherized coils and kits. The DNCADCN948 also features Sun's innovative floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This model's robust design paired with versatile configuration options makes it an excellent choice for demanding hydraulic applications requiring precise control and dependable operation.

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.
