The Sun Hydraulics DNCAMCV612 (DNCAMCV612) is a solenoid-operated, 4-way, 2-position cartridge valve that is direct-acting with a balanced spool directional design. This valve is engineered for applications requiring a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a critical feature 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 but not recommended due to potential performance degradation. It operates under a maximum pressure of 5000 psi (350 bar) and does not require any minimum hydraulic pressure for activation due to its direct actuation. The DNCAMCV612 features a solenoid tube assembly rated for fatigue at high pressures and incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are incompatible with petroleum-based substances. The wet armature design aids in heat dissipation but requires consideration in applications where the coil remains energized for extended periods, as some fluids may degrade under these conditions. This valve offers high efficiency in spool actuation due to its unique magnetic solenoid design, ensuring reliable shifting. Interchangeable coils compatible with other Sun Series 1 products provide flexibility in configuration, including various termination and voltage options, some of which are rated up to IP69K for enhanced environmental protection. Installation considerations include the Sun floating style construction to prevent internal binding from excessive torque or machining variations. With a capacity of 8 gpm (30 L/min), typical response time of 50 ms, and manual override capabilities, this model provides robust performance across numerous 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.
