The Sun Hydraulics DNDATZV228 (DNDATZV228) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered for high performance, this valve is fatigue-rated for up to 5000 psi (350 bar) service and does not require minimum hydraulic pressure for operation. It features a wet armature design where the working fluid surrounds the armature, which can be crucial when the coil is energized for prolonged periods. This valve offers several manual override configurations but note that weatherized coils are incompatible with manual override functionality. The detent mechanism in the manual override provides temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. EPDM seals are used in systems with phosphate ester fluids; however, exposure to petroleum-based fluids will damage these seals. The DNDATZV228 model incorporates Sun\u2019s floating style construction to minimize internal part binding due to excessive installation torque or cavity-cartridge machining variations. This valve supports various coil termination and voltage options with surge protection available, and its coils are interchangeable with other Sun Series 1 solenoid products. Coil connector options provide protection ratings up to IP69K for enhanced environmental resilience. The cartridge has a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar). Typical response time is around 50 ms, with maximum leakage at specified conditions being 10 in\u00b3/min (160 cc/min). It supports switching frequencies up to 15,000 cycles per hour and requires a manual override force of approximately 5 lbs/1000 psi at port one. The valve's installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), making it robust and reliable for various applications requiring precise directional control of hydraulic flow.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges 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.
