The Sun Hydraulics DNCAMBN912 (DNCAMBN912) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting applications. This balanced spool directional valve features a closed transition between positions, which significantly reduces oil loss during shifting, making it ideal for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; although reverse flow is possible, it is not recommended due to performance limitations. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. Notably, this valve operates without requiring any minimum hydraulic pressure. Cartridges fitted with EPDM seals are compatible with systems using phosphate ester fluids but should avoid exposure to petroleum-based substances to prevent seal damage. The wet armature design allows the working fluid to surround the armature, which can lead to heat exposure from the coil if energized for prolonged periods\u2014a consideration when using certain fluids like water-glycol mixtures that may degrade over time. The DNCAMBN912 offers various coil termination and voltage configurations, including options with surge protection. Its high-efficiency solenoid design delivers substantial spool actuating force per watt consumed, enhancing reliability in valve shifting operations. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Connector options provide ratings up to IP69K for enhanced environmental protection. The floating style construction of this valve minimizes potential internal binding caused by excessive installation torque or machining variations in cavity or cartridge dimensions. With a capacity of 8 gpm (30 L/min) and a maximum leakage rate of 10 in\u00b3/min at 110 SUS (3000 psi), this model ensures efficient performance across various applications while maintaining low leakage levels.

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.
