The Sun Hydraulics DMDATPV72499 (DMDATPV72499) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct acting and balanced spool directional control. This model is particularly noted for its robust construction, featuring a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, which ensures durability and reliability under high-pressure conditions. The valve offers a maximum flow capacity of 12 gpm (45 L/min) and operates efficiently with typical response times of 50 ms. Key features include closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve does not require a minimum hydraulic pressure to operate, making it versatile across various hydraulic systems. It incorporates manual override options with detent mechanisms designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. For environmental resilience, cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. The wet armature design helps in heat management around the coil but requires consideration regarding fluid selection to prevent breakdown from prolonged exposure to high temperatures. This model also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and features the innovative Sun floating style construction which minimizes internal part binding due to installation variances. These design choices make the DMDATPV72499 an adaptable solution suitable for a wide range of industrial applications requiring precise hydraulic flow control.

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.
