The Sun Hydraulics DNCATAV223 (DNCATAV223) is a solenoid-operated, 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool design. This directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial aspect for pilot control circuits. The valve is engineered with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance issues. Designed for durability, the solenoid tube assembly withstands fatigue at pressures up to 5000 psi (350 bar). Importantly, this valve operates without requiring a minimum hydraulic pressure. The DNCATAV223 utilizes EPDM seals suitable for systems using phosphate ester fluids; these seals can be damaged by petroleum-based fluids. The wet armature design exposes the armature to working fluid and heat from the coil\u2014important when considering long-term coil energization and potential fluid degradation in water-glycol mixtures. The solenoid's magnetic design ensures high efficiency with substantial spool actuating force per Watt used, enhancing reliability in valve shifting. Various coil termination and voltage options are available with or without surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, coil connector options provide ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to prevent internal parts from binding due to installation torque or machining variations. Key specifications include an 8 gpm (30 L/min) capacity, a maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min). The DNCATAV223 also features a manual override with specific force requirements and stroke dimensions for added operational flexibility.

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.
