The Sun Hydraulics DNDAMUV71219 (DNDAMUV71219) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Featuring a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), this valve requires no minimum hydraulic pressure for operation. It offers multiple manual override options, although models with weatherized coils are not compatible with this feature. The manual override's detent mechanism is designed for temporary actuation and has an approximate mechanical life expectancy of 7,000 cycles. This cartridge is equipped with EPDM seals specifically for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage the seals. The valve employs a wet armature design where the working fluid surrounds the armature, which may be affected by prolonged coil energization due to heat exposure. A variety of coil termination and voltage options are available, some including surge protection. The high-efficiency solenoid design ensures strong spool actuating force per watt expended, promoting reliable valve shifting. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction on the tube. With a cavity size of T-31A and a capacity of 10 gpm (40 L/min), this valve can handle maximum operating pressures up to 5000 psi (350 bar). It features a typical response time of 50 ms and allows a maximum valve leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The switching frequency reaches up to 15,000 cycles per hour. The Sun floating style construction minimizes the risk of internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces.

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.
