The Sun Hydraulics DNCALCN712N (DNCALCN712N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014crucial for maintaining efficiency in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, though it supports reverse flow under non-recommended conditions. Constructed to be robust, the DNCALCN712N's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring long-term durability even under high-pressure operations. It operates without requiring a minimum hydraulic pressure and incorporates EPDM seals specifically suited for phosphate ester fluids; however, these seals are vulnerable to damage by petroleum-based substances. The valve benefits from a wet armature design where the working fluid envelops the armature, potentially affecting fluid integrity if exposed to prolonged coil energization. A variety of coil termination and voltage options are available to suit different system requirements, including options with surge protection. Its magnetic design enhances efficiency by maximizing spool actuating force per watt expended. Additional features include interchangeable coils with other Sun Series 1 solenoid products and multiple connector options that offer up to IP69K ratings for environmental resilience. The DNCALCN712N also employs Sun\u2019s floating style construction which helps prevent internal part binding due to installation errors or cavity/cartridge machining variations. Technical specifications include an 8 gpm (30 L/min) capacity, maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and manual override features ensuring operational control. This model is designed for both reliability in switching performance up to 15000 cycles/hr and minimal leakage at high pressures.

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.
