The Sun Hydraulics DMDADPV71299 (DMDADPV71299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This valve is particularly noted for its robust construction, including a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The DMDADPV71299 features closed transitions between spools B and R, optimizing performance by providing faster and more consistent response times during pilot control applications where capacity is not a critical factor. This model operates without the need for minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It includes options for manual override via D, L, or T control configurations which are primarily intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature; however, it should be noted that prolonged coil energization could lead to fluid degradation in certain conditions. Additionally, the DMDADPV71299 can be fitted with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could cause damage. The valve supports an interchangeable coil system compatible with other Sun Series 1 solenoid products and features Sun's floating style construction which minimizes internal parts binding. This model provides a flow capacity of up to 12 gpm (45 L/min) and offers quick response times typically around 50 ms. Its design also allows up to 15,000 switching cycles per hour, making it an efficient choice for high-frequency applications.

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.
