The Sun Hydraulics DNCALAV612N (DNCALAV612N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a closed transition between positions to minimize oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve is designed with a capacity based on port 3 as the inlet and port 1 as the tank, and although it allows reverse flow, optimal performance in this mode is not guaranteed. Engineered for durability and reliability, the DNCALAV612N has a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service. It operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The cartridge uses EPDM seals suitable for systems with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. This model incorporates a wet armature design where the working fluid surrounds the armature. Extended energization of the coil may affect fluid integrity due to heat exposure. The DNCALAV612N offers various coil termination and voltage options, including models with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include an IP69K rating available for some coil connector options and enhanced environmental protection through optional weatherized coils and kits. The valve also benefits from Sun\u2019s floating style construction which reduces internal part binding risks caused by excessive installation torque or cavity/cartridge machining variations. With specifications like an 8 gpm (30 L/min) capacity at maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and manual override capabilities, the DNCALAV612N is engineered for efficient performance in demanding hydraulic 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.
