The Sun Hydraulics DNDATTV71299 (DNDATTV71299) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate efficiently under high-pressure conditions, with its solenoid tube assembly rated for fatigue service at 5000 psi (350 bar). It requires no minimum hydraulic pressure to function, making it versatile for various applications. The valve features multiple manual override options, although these are not compatible with weatherized coils. Models with the D or L control include a detent mechanism intended for temporary actuation and have a mechanical life expectancy of approximately 7,000 cycles. The DNDATTV71299 utilizes a wet armature design, where the working fluid surrounds the armature and can be affected by heat generated during prolonged coil energization. This is particularly relevant when using fluids like water-glycol mixtures that may degrade over time due to heat exposure. The valve offers numerous coil termination and voltage options, some of which include surge protection, while allowing interchangeable use with other Sun Series 1 solenoid products. This valve incorporates Sun's floating style construction to prevent internal part binding from excessive installation torque or machining variations. It fits into a T-31A cavity and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The maximum operating pressure is set at 5000 psi (350 bar), with a typical response time of 50 ms and maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Its switching frequency reaches up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs/1000 psi on Port 1 and has a stroke length of .10 inches (2.5 mm).

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.
