The Sun Hydraulics DMDADRV71299 (DMDADRV71299) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control. Designed for high-performance applications, this valve is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding hydraulic systems. The DMDADRV71299 operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The valve's design includes closed transitions between spool positions B and R, which optimize performance by providing faster and more consistent response times especially in pilot control scenarios where capacity is less critical. The model is equipped with a manual override detent mechanism intended for temporary actuation, with an estimated mechanical life of about 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. The wet armature design of the valve means the working fluid surrounds the armature which might affect fluid integrity if exposed to heat over extended periods. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility of this model. It also incorporates Sun's floating style construction that helps minimize internal parts binding due to installation torque or variations in cavity/cartridge machining. This model supports a flow capacity of up to 12 gpm (45 L/min) and features quick response times typically around 50 ms. With its robust construction and reliable performance characteristics, the DMDADRV71299 is engineered to meet rigorous industrial demands while ensuring operational efficiency and reliability.

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.
