The Sun Hydraulics DNCATBV212N (DNCATBV212N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional flow. The valve transitions between positions in a closed state, significantly reducing oil loss during shifts, which is particularly beneficial in pilot control circuits. Optimal performance is achieved 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 can withstand up to 5000 psi (350 bar), and the valve operates without requiring minimum hydraulic pressure. It features EPDM seals compatible with phosphate ester fluids but susceptible to damage from petroleum-based substances. The wet armature design exposes working fluid to coil-generated heat, potentially affecting fluid integrity over prolonged periods of coil energization. This model offers various coil termination and voltage options, including those with surge protection. Its unique magnetic design ensures efficient operation with high spool actuating force per watt used. Interchangeable coils fit other Sun Series 1 products and can be mounted bidirectionally on the tube. The valve supports IP69K-rated coil connectors for enhanced environmental protection and incorporates floating style construction to minimize internal part binding from installation torque or machining variations. The DNCATBV212N fits into cavity T-31A and belongs to Series 1 with a capacity of up to 8 gpm (30 L/min). It has a typical response time of 50 ms and allows a maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports a switching frequency of up to 15,000 cycles/hour. Manual override requires a force of 5 lbs/1000 psi at Port 1 with a stroke length of .10 in (2.5 mm). The solenoid tube diameter is .75 in (19 mm), while the valve hex size is .78 in (22.2 mm), requiring an installation torque between 30\u201335 lbf\u00b7ft (41\u201347 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for both cartridge and coil components.

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.
