The Sun Hydraulics DNCADTN211 (DNCADTN211) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing fluid loss during position shifts which is crucial in maintaining the efficiency of pilot control circuits. The valve's configuration allows for port 3 to be used as the inlet and port 1 as the tank outlet, supporting a flow capacity of up to 8 gallons per minute (30 liters per minute) and can withstand an operating pressure up to 5000 psi (350 bar). The DNCADTN211 features a fatigue-rated solenoid tube assembly suitable for high-pressure applications up to 5000 psi. It operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The wet armature design of the valve means that the working fluid surrounds the armature which could be significant when considering thermal management within the system. The valve is equipped with EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. For adaptability in different environments, Sun Hydraulics offers various coil termination and voltage options for this model, including designs with surge protection and weatherized coils for enhanced environmental protection. The coils are interchangeable with other Series 1 solenoid products from Sun Hydraulics and can be mounted in either direction on the tube. Further enhancing its reliability and ease of installation, this model incorporates Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This design feature ensures consistent performance even under variable installation conditions. With its robust design and flexible configuration options, the DNCADTN211 is engineered for efficient operation and long service life in demanding hydraulic 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.
