The Sun Hydraulics DNCALWV612N (DNCALWV612N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This valve is optimized for applications requiring minimal oil loss during position transitions, making it especially suitable for pilot control circuits. It offers a maximum operating pressure of 5000 psi (350 bar) and a capacity of 8 gpm (30 L/min), with the configuration based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, it is not recommended as performance may not be guaranteed. The valve's solenoid tube assembly is fatigue-rated for high-pressure service and utilizes a wet armature design to enhance efficiency and reliability. This design choice ensures that the working fluid surrounds the armature, although care should be taken with fluids like water-glycol mixtures that may degrade at high temperatures over time. The solenoid's magnetic design offers high efficiency and reliable shifting with interchangeable coils compatible with other Sun Series 1 products. Incorporating Sun's floating style construction minimizes internal part binding due to installation torque or machining variations. The valve also includes various coil termination and voltage options with surge protection, offering up to IP69K ratings for enhanced environmental protection. Manual override features require minimal force, ensuring ease of operation under different conditions. The DNCALWV612N model weighs .60 lb (.30 kg) and requires an installation torque of 30 - 35 lbf ft (41 - 47 Nm). It supports a switching frequency of up to 15,000 cycles per hour with a typical response time of 50 ms. Seal kits are available in Viton material for both cartridge and coil components to ensure compatibility with specific fluid types used in various hydraulic systems.

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.
