The Sun Hydraulics DNCAMLV297 (DNCAMLV297) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool valve features a closed transition between positions, significantly minimizing oil loss during shifting\u2014an essential characteristic for pilot control circuits. It is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow is possible but not recommended due to potential performance issues. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring robust service under high-pressure conditions. Notably, this valve operates without requiring minimum hydraulic pressure and utilizes EPDM seals suitable for phosphate ester fluids while being incompatible with petroleum-based substances. The DNCAMLV297 incorporates a wet armature design where the working fluid cools the armature exposed to coil-generated heat. Users should be cautious of fluid breakdown over time in high-temperature environments, especially with water-glycol mixtures that may form varnishes affecting cartridge function. This model offers versatile coil termination and voltage options, with surge protection available. The high-efficiency solenoid design delivers exceptional spool actuating force per watt, ensuring reliable operation. This valve uses Sun's floating style construction to prevent internal part binding from installation torque or machining variations. It supports up to IP69K-rated coil connector options and can interchange coils with other Sun Series 1 products. The DNCAMLV297 fits into cavity T-31A and belongs to Series 1, offering a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar). Its typical response time is around 50 ms, with maximum leakage at specified conditions being minimal. The model weighs approximately .60 lb (.30 kg), making it a compact yet powerful component for hydraulic applications requiring precise directional control.

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.
