The Sun Hydraulics DNDAMYV71219 (DNDAMYV71219) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a robust solenoid tube assembly rated for a fatigue service of up to 5000 psi (350 bar), ensuring high reliability in demanding applications. This valve does not require any minimum hydraulic pressure for operation, making it versatile and easy to integrate into various systems. Users have multiple manual override options, although compatibility with weatherized coils is limited. The manual control assemblies equipped with D or L control are intended for temporary actuation and have an approximate mechanical life of 7,000 cycles. The valve incorporates EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. It employs a wet armature design where the working fluid surrounds the armature, which can lead to heat-related issues if the coil is energized for extended periods\u2014particularly with water-glycol mixtures that may degrade over time. The solenoid boasts a unique magnetic design providing high efficiency and reliable shifting due to increased spool actuating force per Watt expended. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. A variety of coil termination and voltage options are available, some offering IP69K ratings for enhanced environmental protection. The cartridge uses Sun's floating style construction to minimize internal part binding from installation torque or machining variations. It fits into T31A cavities and has a capacity of up to 10 gpm (40 L/min). Additional specifications include a typical response time of 50 ms, maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), switching frequency up to 15,000 cycles/hr, and specific manual override force requirements.

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.
