The Sun Hydraulics DMDAXNV71299 (DMDAXNV71299) 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 is engineered to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). It features a quick response time of approximately 50 ms and is capable of handling switching frequencies up to 15000 cycles per hour. Constructed with durability in mind, the DMDAXNV71299 incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to variations in installation torque or cavity/cartridge machining. The valve's manual override mechanism, available in models with D or L control, provides temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, the valve is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The solenoid tube assembly of the DMDAXNV71299 is fatigue-rated for high-pressure service and uses a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization can lead to fluid breakdown at high temperatures. For versatility in system design, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Overall, the Sun Hydraulics DMDAXNV71299 offers a reliable solution for controlling flow within hydraulic systems where high performance and reliability are essential. Its robust construction and thoughtful design details ensure consistent operation under demanding 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.
