The Sun Hydraulics DNCALSN212 (DNCALSN212) is a solenoid-operated, 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool design. This valve features a closed transition between positions, effectively minimizing oil loss during shifting\u2014a critical aspect for pilot control circuits. It is designed with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, optimal performance is not assured and thus not recommended. The solenoid tube assembly is fatigue rated for service pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. Notably, this valve does not require any minimum hydraulic pressure for operation due to its direct actuation mechanism. The DNCALSN212 incorporates EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. The valve employs a wet armature design where the working fluid surrounds the armature and absorbs heat generated by the coil\u2014attention should be given to fluid types like water-glycol mixtures that may degrade at high temperatures over time. A diverse range of coil termination and voltage options are available, enhancing adaptability across different applications. The unique magnetic design of the solenoid delivers high efficiency through increased spool actuating force per watt, facilitating reliable valve operation. Additional features include interchangeable coils with other Sun Series 1 products and mounting flexibility on the tube in either direction. Coil connector options provide protection ratings up to IP69K, with additional weatherized coils available for enhanced environmental resilience. The floating style construction minimizes binding risks due to installation torque or machining variations. This model supports a capacity of 8 gpm (30 L/min) and allows a maximum operating pressure of 5000 psi (350 bar), making it suitable for high-demand 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.
