The Sun Hydraulics DMDADPV912N (DMDADPV912N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve characterized by its direct-acting, balanced spool design. This precision-engineered valve offers robust control in hydraulic systems, operating effectively without the need for a minimum hydraulic pressure. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding applications. The valve's design includes spools B and R, which are closed during the transition between positions to enhance performance limits at the cost of lower capacity. This configuration is particularly advantageous in pilot control applications where speed and consistency are more critical than flow capacity. The DMDADPV912N incorporates a wet armature setup, where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure. For manual override operations, models with D or L controls include a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and utilizes Sun's floating style construction to minimize internal part binding caused by installation torque or machining variations. This valve is ideal for use in systems employing phosphate ester fluids thanks to its EPDM seals; however, these seals must not be exposed to petroleum-based fluids which can cause damage. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, the DMDADPV912N stands out as a reliable choice for efficient directional control in hydraulic circuits.

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.
