The Sun Hydraulics DNDAMZV912 (DNDAMZV912) is a solenoid-operated 4-way, 2-position cartridge valve known for its direct-acting, balanced spool directional capabilities. This valve is designed to operate without requiring a minimum hydraulic pressure, making it versatile for various applications. It is equipped with a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. The DNDAMZV912 offers several manual override options, although models with the D or L control feature a detent mechanism intended for temporary actuation with an approximate mechanical life of 7,000 cycles. It supports EPDM seals for systems using phosphate ester fluids but requires caution as petroleum-based fluids can damage these seals. The valve employs a wet armature design, where the working fluid surrounds the armature and can be affected by coil-generated heat during extended energization periods. This design choice provides high efficiency and reliable valve shifting due to its unique magnetic configuration. A wide range of coil termination and voltage options are available, including those with surge protection, and coils are interchangeable with other Sun Series 1 solenoid products. This model incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. The DNDAMZV912 features a cavity size of T-31A and has a capacity of 10 gpm (40 L/min). Its maximum operating pressure reaches up to 5000 psi (350 bar), with typical response times around 50 ms and leakage rates at maximum operating conditions capped at 10 in\u00b3/min (160 cc/min). The valve also boasts a high switching frequency of up to 15,000 cycles per hour and comes in at a weight of .60 lb (.30 kg).

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.
