The Sun Hydraulics DMDATPN71299 (DMDATPN71299) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate with no minimum hydraulic pressure required for functionality. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for demanding applications. The spools B and R maintain a closed transition between positions, optimizing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The valve incorporates a wet armature design, whereby the working fluid surrounds the armature. This setup requires consideration of fluid type as heat generated by the coil during prolonged energization can degrade certain fluids like water-glycol mixtures. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. Additionally, the DMDATPN71299 offers interchangeable coils with other Sun Series 1 solenoid products and allows for flexible mounting orientations on the tube. It also features Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. The manual override mechanism is designed for temporary actuation with a mechanical life expectancy around 7,000 cycles. This model supports up to 12 gpm (45 L/min) capacity and boasts quick response times typically around 50 ms. It also allows for a high switching frequency of up to 15,000 cycles per hour. Other technical specifications include maximum operating pressure of 5000 psi (350 bar), maximum valve leakage at specific conditions, and manual override requirements detailed in terms of force and stroke dimensions.

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.
