The Sun Hydraulics DNDATZV948 (DNDATZV948) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve is robustly engineered with a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability under high-pressure conditions. Notably, it operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The cartridge offers multiple manual override options, though compatibility with weatherized coils is limited. Its detent mechanism provides temporary actuation with an approximate mechanical life of 7,000 cycles. The DNDATZV948 features a wet armature design where the working fluid surrounds the armature, absorbing heat generated by the coil\u2014essential to consider for prolonged coil energization as certain fluids may degrade over time. This model supports various coil termination and voltage configurations and includes options with surge protection. Its high-efficiency magnetic design ensures reliable valve shifting by delivering substantial spool actuating force per watt expended. This cartridge's construction minimizes internal binding risks due to installation torque or cavity machining variations, thanks to its floating style design. It fits into a T31A cavity and belongs to Series 1, offering a capacity of 10 gpm (40 L/min) and operating pressures up to 5000 psi (350 bar). The response time is typically around 50 ms, with maximum leakage at standard conditions being minimal. Additional specifications include a switching frequency of up to 15,000 cycles per hour and manual override force requirements of approximately 5 lbs/1000 psi at Port 1. The valve's dimensions are compact with a hex size of .78 inches (22.2 mm), making it suitable for space-constrained installations. Seal kits in Viton are available for both the cartridge and coil components to ensure optimal sealing performance in various fluid environments.

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.
