The Sun Hydraulics DMDADPN612N (DMDADPN612N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve ensures efficient operation with its closed spools B and R during transitions, enhancing performance by reducing capacity only where it doesn't affect functionality. Particularly effective as pilot controls, the valve's design allows for rapid and consistent response times without requiring a minimum hydraulic pressure to operate. With a robust construction rated for fatigue at 5000 psi (350 bar), the DMDADPN612N is equipped to handle demanding usage conditions. The manual override feature included in models with D or L control is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. It also features EPDM seals suitable for systems using phosphate ester fluids, while caution is advised against exposure to petroleum-based substances which could degrade the seals. This valve incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization. It supports up to 12 gpm (45 L/min) flow capacity and can withstand maximum operating pressures up to 5000 psi (350 bar). The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. Additionally, the innovative Sun floating style construction minimizes internal part binding due to installation or cavity machining variations. Designed for reliability and durability in complex hydraulic systems, this valve is an essential component for ensuring precise fluid control in various industrial 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.
