The Sun Hydraulics DNDATTV612 (DNDATTV612) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. Engineered for reliability, the solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), making it suitable for demanding applications. This valve operates without requiring minimum hydraulic pressure and offers several manual override options, although note that manual override is incompatible with weatherized coils. The D and L control models include a detent mechanism in the manual override designed for temporary actuation, with an approximate mechanical life expectancy of 7,000 cycles. Cartridges fitted with EPDM seals are intended for systems using phosphate ester fluids; contact with petroleum-based substances can damage these seals. The valve employs a wet armature design that allows the working fluid to absorb heat from the coil, which could impact performance if energized for extended periods\u2014especially in systems using water-glycol mixtures. A range of coil termination and voltage configurations are available, some featuring surge protection. The solenoid's magnetic design ensures high efficiency and reliable valve shifting by maximizing spool actuating force per watt expended. Coils are interchangeable within the Sun Series 1 range and can be mounted bidirectionally on the tube. Additional features include IP69K-rated coil connector options and weatherized coils for enhanced environmental protection. The cartridge's floating style construction minimizes internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. With a capacity of 10 gpm (40 L/min), response time around 50 ms, and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), this versatile valve is well-suited for high-frequency switching applications up to 15,000 cycles/hr.

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.
