The Sun Hydraulics DMDAXPV812N (DMDAXPV812N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve is characterized by its robust design that includes a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications as pilot controls where capacity is less critical. The DMDAXPV812N operates without requiring a minimum hydraulic pressure, making it highly effective in various operational scenarios. It includes options for manual overrides with a detent mechanism designed primarily for temporary actuation; these are expected to last approximately 7,000 cycles. The valve\u2019s compatibility with EPDM seals makes it suitable for systems using phosphate ester fluids, while its wet armature design helps manage heat dissipation around the coil. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun\u2019s floating style construction to reduce the risk of internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 3000 psi set at 5 in\u00b3/min. With features like a switching frequency up to 15000 cycles/hr and manual override requirements carefully defined, the DMDAXPV812N is engineered for reliability and optimal performance in demanding hydraulic control applications.

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.
