The Sun Hydraulics DNCALWV948 (DNCALWV948) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient and reliable directional control in hydraulic systems. This direct-acting, balanced spool valve features a closed transition between positions, minimizing oil loss during shifting, which is crucial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to performance limitations. Engineered for high-pressure applications, the solenoid tube assembly supports up to 5000 psi (350 bar) service pressure without requiring minimum hydraulic pressure for operation. This cartridge valve incorporates EPDM seals suitable for systems using phosphate ester fluids while being incompatible with petroleum-based fluids. Its wet armature design allows fluid exposure to coil-generated heat, a consideration when using certain fluids like water-glycol mixtures that may degrade over time. The valve offers flexibility with various coil termination and voltage options, including surge protection. Coils are interchangeable within Sun Series 1 products and provide high spool actuating force per Watt due to their efficient magnetic design. The DNCALWV948 supports a maximum flow capacity of 8 gpm (30 L/min) and boasts a rapid response time of approximately 50 ms. It maintains low leakage rates under standard conditions and can endure up to 15,000 cycles per hour switching frequency. Installation is simplified through its floating-style construction that minimizes binding risks from installation torque or machining variations. The valve includes manual override functionality with specific force requirements and stroke length for emergency operations. Its robust construction ensures reliable performance across various demanding applications where precise fluid control is essential.

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.
