The Sun Hydraulics DNCALZV712N (DNCALZV712N) is a solenoid-operated, 4-way, 2-position cartridge valve designed as a direct-acting, balanced spool directional valve. It features a closed transition between positions to minimize oil loss during shifting, which is particularly beneficial in 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 issues. This valve operates at a maximum pressure of 5000 psi (350 bar) and does not require minimum hydraulic pressure for operation, making it highly versatile for various applications. The solenoid tube assembly is fatigue-rated for high-pressure service, and the design incorporates a wet armature to enhance efficiency by surrounding the armature with working fluid. However, users should be aware that prolonged coil energization can lead to fluid breakdown in certain mixtures like water-glycol. The DNCALZV712N offers various coil termination and voltage options, including those with surge protection and weatherized kits for environmental resilience. The valve employs Sun's floating style construction to prevent internal part binding due to installation or machining variations. It has a capacity of 8 gpm (30 L/min) and typical response time of 50 ms. The leakage rate at maximum operating conditions is minimal, ensuring efficient operation with low maintenance needs. Additionally, the interchangeable coils are compatible with other Sun Series 1 solenoid products. This model also provides manual override capabilities with specific force requirements and stroke length for ease of use in manual operations. With its robust design and reliable performance characteristics, this directional valve serves as an essential component in hydraulic systems requiring precise control and durability 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.
