The Sun Hydraulics DMDALRV72499 (DMDALRV72499) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is distinguished by its ability to operate without minimum hydraulic pressure, making it highly versatile for various applications. It features a robust design with a fatigue rating of 5000 psi (350 bar), suitable for demanding environments. The valve's solenoid tube assembly ensures durability and reliability under continuous use, while the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. Notably, the valve incorporates a wet armature design which helps in cooling but requires consideration regarding the type of fluid used due to potential breakdown at high temperatures. This model is equipped with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. The manual override feature in models with D or L control is intended for temporary actuation only, with a mechanical life expectancy of approximately 7,000 cycles. Additionally, the Sun floating style construction minimizes internal parts binding, enhancing the operational reliability. Key specifications include a maximum operating pressure of 5000 psi (350 bar), a flow capacity of 12 gpm (45 L/min), and typical response times of 50 ms. The valve also supports a high switching frequency up to 15000 cycles per hour and features manual override capabilities that require minimal force. This makes the DMDALRV72499 an ideal choice for applications requiring reliable and efficient directional control in hydraulic systems.

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.
