The Sun Hydraulics DMDALAV712N (DMDALAV712N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is specifically engineered for applications requiring robust control and high-pressure operation, with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The DMDALAV712N operates without the need for minimum hydraulic pressure, making it highly effective in various fluid power applications. The valve's construction includes a wet armature design where the working fluid surrounds the armature. This design is crucial for its operation but requires consideration of the fluid type used to avoid breakdowns or varnish formation that could impair functionality. Compatible with EPDM seals for systems using phosphate ester fluids, the DMDALAV712N ensures reliability and longevity even under rigorous conditions. However, exposure to petroleum-based fluids should be avoided as it can damage the seals. For enhanced versatility, this model's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve also features Sun\u2019s floating style construction which helps minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a response time of typically 50 ms and a manual override feature with a detent mechanism designed for temporary actuation. The manual control assembly has an estimated mechanical life of approximately 7,000 cycles. Additionally, this model offers easy maintenance options with available seal kits tailored for specific operational needs.

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.
