The Sun Hydraulics DNCALAV612 (DNCALAV612) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in maintaining efficiency in pilot control circuits. The valve's design allows for port 3 to be used as the inlet and port 1 as the tank outlet, although it does support reverse flow under non-recommended conditions. With a robust construction, the solenoid tube assembly of this valve is fatigue rated for operations up to 5000 psi (350 bar), ensuring durability and reliability even under high-pressure scenarios. The DNCALAV612 operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. It incorporates EPDM seals specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model employs a wet armature design where the working fluid surrounds the armature. This design consideration is essential when the coil is energized for extended periods, as heat generated can affect certain fluid types. The DNCALAV612 offers various coil termination and voltage options, including models with surge protection to cater to different operational requirements and environments. Additionally, this valve benefits from Sun Hydraulics\u2019 innovative floating style construction which reduces risks associated with internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This feature ensures consistent performance and longevity of the valve in diverse hydraulic systems. With interchangeable coils compatible with other Sun Series 1 solenoid products and multiple environmental protection options available, the DNCALAV612 stands out as a reliable choice for efficient and precise hydraulic flow control in demanding applications.

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.
