The Sun Hydraulics DNCALTN712N (DNCALTN712N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This directional valve is characterized by its closed transition between positions, which minimizes oil loss during shifting\u2014an essential feature for pilot control circuits. Designed with port 3 as the inlet and port 1 as the tank, it offers optimal performance in this configuration; however, reverse flow is possible but not recommended due to potential performance degradation. The valve's solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This direct-actuated valve requires no minimum hydraulic pressure to operate and incorporates EPDM seals suitable for systems using phosphate ester fluids while being incompatible with petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature, exposing it to coil-generated heat\u2014a consideration for long-duration energization that may affect fluid integrity over time. The DNCALTN712N boasts a unique magnetic design that enhances solenoid efficiency by providing high spool actuating force per watt expended. This ensures reliable valve shifting and compatibility with interchangeable coils from other Sun Series 1 solenoid products. Coil connector options provide protection ratings up to IP69K, with additional weatherized coils and kits available for enhanced environmental protection. Incorporating Sun's floating style construction, this valve minimizes the risk of internal part binding due to excessive installation torque or cavity-cartridge machining variations. It features a capacity of 8 gpm (30 L/min), a typical response time of 50 ms, and can handle a maximum operating pressure of 5000 psi (350 bar). The model weighs approximately .60 lb (0.30 kg) and comes with Viton seal kits for both cartridge and coil 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.
