The Sun Hydraulics DNCAMAV912 (DNCAMAV912) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, which minimizes oil loss during shifting\u2014an important aspect for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to potential performance degradation. It operates effectively under high pressure with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). Notably, this valve does not require minimum hydraulic pressure for operation. The DNCAMAV912 incorporates EPDM seals suitable for systems using phosphate ester fluids, though these seals can be damaged by petroleum-based substances. Its wet armature design allows the working fluid to cool the coil but may lead to issues in certain fluids over time if exposed to prolonged heat. The solenoid's efficient magnetic design ensures reliable shifting with high actuating force per watt. Coils are interchangeable within Sun Series 1 products and can be mounted bi-directionally on the tube, offering various termination and voltage options including surge protection. This model supports a switching frequency of up to 15,000 cycles per hour and has a typical response time of 50 milliseconds. It features Sun\u2019s floating style construction to reduce internal binding risks during installation or due to machining variations in the cavity or cartridge. The maximum operating capacity is rated at 8 gpm (30 L/min), with minimal leakage at specified conditions. The DNCAMAV912 is lightweight at just .60 lb (.30 kg), making it suitable for diverse applications requiring compact yet robust hydraulic control solutions.

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.
