The Sun Hydraulics DNCATCV212N (DNCATCV212N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is engineered with a closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature for pilot control circuits. It is optimized for operation with port 3 as the inlet and port 1 as the tank; although reverse flow is possible, it is not recommended due to potential performance degradation. The solenoid tube assembly of this valve is fatigue-rated for service up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. Designed for direct actuation, it requires no minimum hydraulic pressure to operate. The DNCATCV212N incorporates EPDM seals compatible with phosphate ester fluids but unsuitable for petroleum-based fluids due to potential seal damage. Its wet armature design allows working fluid to surround the armature, exposing it to coil-generated heat\u2014an important consideration when using fluids like water-glycol mixtures which may degrade over time under such conditions. The solenoid's innovative magnetic design enhances efficiency by delivering substantial spool actuating force per watt expended, ensuring reliable valve shifting. Available coil options provide various termination and voltage configurations, some offering surge protection and environmental ratings up to IP69K for enhanced durability in harsh conditions. This model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The floating style construction minimizes internal binding risks caused by excessive installation torque or cavity/cartridge machining variations. With a capacity of 8 gpm (30 L/min) and a rapid response time of typically 50 ms, this cartridge valve is suited for applications requiring quick and efficient hydraulic fluid control under demanding conditions.

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.
