The Sun Hydraulics DMDALRN712N (DMDALRN712N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It is designed with spools B and R which are closed during the transition between positions, optimizing performance by providing faster and more consistent response times, especially suitable for applications where capacity is less critical. The DMDALRN712N incorporates a wet armature design that allows the working fluid to surround the armature, aiding in heat management when the coil is energized for extended periods. However, this design requires careful selection of fluids as some, like water-glycol mixtures, may degrade at higher temperatures. The valve's construction includes EPDM seals intended for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. For ease of integration and maintenance, this model features interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual override mechanism built into this model is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Additionally, it employs Sun\u2019s floating style construction which minimizes internal parts binding due to installation variances or excessive torque. This robust valve is suitable for various hydraulic applications requiring reliable directional control and rapid response times under high-pressure conditions. Its compact size (.60 lb/0.30 kg), quick typical response time of 50 ms, and maximum leakage rate at 110 SUS (24 cSt) of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), make it an efficient choice for specialized 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.
