The Sun Hydraulics DMDAXPV299 (DMDAXPV299) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise fluid control in hydraulic systems. This direct-acting, balanced spool directional valve is configured with EPDM seals suitable for use with phosphate ester fluids, ensuring durability and resistance against petroleum-based substances. The valve features a fatigue rating of 5000 psi (350 bar) and incorporates a closed transition between spool positions B and R, enhancing performance by ensuring faster and more consistent response times during pilot control operations. The DMDAXPV299 operates without the need for minimum hydraulic pressure, facilitating its use in a variety of applications. It includes manual override options with D, L, or T controls where the detent mechanism supports temporary actuation. This model boasts an impressive mechanical life expectancy of about 7,000 cycles for the manual control assembly. Additionally, it utilizes a wet armature design where the working fluid surrounds the armature exposed to heat from the coil; this is crucial in applications where the coil remains energized over extended periods. Moreover, this cartridge valve supports a maximum flow capacity of 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Its quick response time is typically around 50 ms, and it offers interchangeable coils with other Sun Series 1 solenoid products for flexible installation options. The construction minimizes internal parts binding thanks to Sun's floating style design which compensates for installation torque and machining variations in cavity-cartridge systems. This model is an essential component for systems requiring reliable directional control of fluids under high pressure conditions.

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.
