The Sun Hydraulics DMDADNV912N (DMDADNV912N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features a robust design with spools B and R that are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where high capacity isn't crucial. Engineered for durability and reliability, the DMDADNV912N incorporates Sun's floating style construction which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It also includes a wet armature design wherein the working fluid surrounds the armature. This design consideration is important as prolonged energization of the coil can heat the fluid, potentially affecting fluid properties over time. The valve offers flexibility in terms of maintenance and compatibility; its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based substances. Additionally, manual override options equipped with detent mechanisms support temporary actuation, with an expected mechanical life of about 7,000 cycles. In summary, the Sun Hydraulics DMDADNV912N provides a reliable solution for directing flow in hydraulic systems requiring precise control and quick response times under high-pressure conditions. Its construction minimizes potential operational issues while offering easy integration and maintenance within various hydraulic setups.

This solenoid-operated 3-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.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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 configured 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
