The Sun Hydraulics DNCAMTN71219 (DNCAMTN71219) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This directional valve is engineered with a closed transition between positions to significantly minimize oil loss during shifting, making it ideal for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank outlet, although reverse flow is possible but not recommended due to performance considerations. It boasts a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure and operates without the need for minimum hydraulic pressure. The cartridge can be configured with EPDM seals specifically for systems using phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. Utilizing a wet armature design, this valve allows the working fluid to surround the armature, which can be advantageous or detrimental depending on fluid type and coil energization duration. Notably efficient in its magnetic design, the solenoid delivers high actuating force per watt, ensuring reliable shifting performance. The DNCAMTN71219 offers various coil termination and voltage options, including surge protection features. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted in either orientation on the tube. For environmental resilience, coil connector options provide ratings up to IP69K. The valve incorporates Sun's floating style construction to mitigate internal binding risks due to installation torque or machining variations in cavity/cartridge interfaces. With a flow capacity of 8 gpm (30 L/min) and a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this valve supports high-frequency switching up to 15,000 cycles per hour while maintaining precise control over hydraulic operations.

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.
