The Sun Hydraulics DMDAMNN299 (DMDAMNN299) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve offers precise control and is equipped with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. It features closed transitions between Spools B and R, enhancing performance by ensuring quicker and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDAMNN299 operates without requiring a minimum hydraulic pressure, adding to its versatility in various applications. It includes options for manual override controls (D, L, T), which are designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve's wet armature design indicates that the working fluid surrounds the armature which could be a consideration in applications where the coil remains energized for extended periods. This model can accommodate flow rates up to 12 gpm (45 L/min) and withstands maximum operating pressures of 5000 psi (350 bar). Its swift response time of approximately 50 ms and low maximum valve leakage at high pressure make it reliable and efficient in maintaining system integrity. Additionally, its interchangeable coils with other Sun Series 1 solenoid products offer flexibility in system design. Key physical attributes include a solenoid tube diameter of .75 inch (19 mm), hex size of 7/8 inch (22.2 mm), and an installation torque requirement between 30 - 35 lbf ft (41 - 47 Nm). The DMDAMNN299 weighs about .60 lb (0.30 kg), ensuring it is robust yet lightweight enough for integration into various setups without significant alterations to existing structures.

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.
