The Sun Hydraulics DMDALAV812N (DMDALAV812N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating for 5000 psi (350 bar) service, ensuring reliability and durability under demanding conditions. The valve's spools B and R remain closed during the transition between positions, optimizing performance by providing faster and more consistent response times especially when used as pilot controls. With no minimum hydraulic pressure required for operation, the DMDALAV812N offers versatility in integration and functionality across different hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles. The wet armature design of the valve means the working fluid surrounds the armature which can be a consideration if the coil remains energized over extended periods, potentially affecting fluid integrity depending on the type. This model is compatible with EPDM seals specifically suited for systems using phosphate ester fluids; however, these seals are sensitive to petroleum-based fluids which can cause damage. Additionally, the interchangeable coils from Sun Series 1 solenoid products enhance this model\u2019s adaptability and maintenance ease. The floating style construction minimizes internal binding risks due to installation torque or machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and a switching frequency capable of handling up to 15,000 cycles per hour. Designed for efficient installation and maintenance with specific torque settings and dimensions provided for optimal use, the DMDALAV812N ensures reliable performance tailored for advanced hydraulic system requirements.

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.
