The Sun Hydraulics DMDALPN299 (DMDALPN299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures efficient control with its capability to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The valve features closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDALPN299 model is equipped with EPDM seals suitable for use with phosphate ester fluids, cautioning against exposure to petroleum-based fluids which may damage the seals. It incorporates a wet armature design; thus, the working fluid surrounds the armature which could lead to fluid breakdown if the coil remains energized for extended periods. The manual override feature present in models with D or L control uses a detent mechanism intended for temporary actuation, supporting about 7,000 mechanical life cycles. Interchangeable coils from Sun's Series 1 solenoid products can be mounted on this valve in either direction. Additionally, it utilizes Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a typical response time of 50 ms and a manual override force requirement of 5 lbs at 1000 psi for Port 1. This compact unit weighs approximately 0.60 lb (0.30 kg) and requires an installation torque between 30 - 35 lbf.ft (41 - 47 Nm), ensuring easy handling and installation in various hydraulic systems configurations.

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.
