The Sun Hydraulics DNCALCN212 (DNCALCN212) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve ensures a closed transition between positions, significantly reducing oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's operation does not require a minimum hydraulic pressure, making it versatile for various applications. With a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), the DNCALCN212 is robust and suitable for high-pressure environments. It features a fast response time of approximately 50 ms and allows for a switching frequency up to 15,000 cycles per hour. Its manual override requires a force of 5 lbs at 1000 psi on Port 1, with an override stroke of .10 in (2.5 mm). The valve's solenoid tube assembly is fatigue rated for durability under continuous use and the wet armature design aids in its efficient operation though it necessitates consideration regarding fluid type due to potential heat exposure effects on certain fluids like water-glycol mixtures. To accommodate different system requirements, cartridges with EPDM seals are available specifically for use with phosphate ester fluids. Moreover, the DNCALCN212 incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This feature enhances the reliability and longevity of the valve in complex installations. Coil connector options provide additional adaptability with environmental protection ratings up to IP69K, ensuring that the valve performs reliably in various operating conditions without compromising on efficiency or safety.

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.
