The Sun Hydraulics DMDATPN299 (DMDATPN299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and capability to handle a maximum operating pressure of 5000 psi (350 bar). The solenoid tube assembly of the valve is fatigue rated for demanding applications, ensuring durability and reliability under high-pressure conditions. Featuring closed transitions between Spools B and R, the DMDATPN299 offers superior performance by minimizing flow capacity during switching. This characteristic makes it particularly suitable for pilot control applications where swift and consistent response times are critical. The valve operates without requiring a minimum hydraulic pressure, enhancing its effectiveness in various operational scenarios. This model incorporates EPDM seals suitable for systems using phosphate ester fluids while cautioning against exposure to petroleum-based fluids which could damage the seals. It also features a wet armature design where the working fluid surrounds the armature, potentially affecting performance if exposed to heat over prolonged periods. The DMDATPN299 is compatible with other Sun Series 1 solenoid products regarding coil interchangeability and can be mounted in either direction on the tube. It also benefits from Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve is designed for efficiency and quick operation in hydraulic systems.

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.
