The Sun Hydraulics DMDAMAV512 (DMDAMAV512) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, making it versatile for various applications. Its fatigue-rated solenoid tube assembly can handle services up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times when used as pilot controls. This design trait, however, does result in a reduced capacity which is a non-issue in pilot control applications where capacity demands are typically lower. The model also includes manual override options with a detent mechanism designed for temporary actuation and has an estimated mechanical life of about 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. Additionally, the wet armature design of the valve means that the working fluid surrounds the armature; this can lead to higher temperatures if the coil remains energized over extended periods, potentially affecting fluid integrity. This valve model boasts interchangeable coils with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity-cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and swift typical response times of about 50 ms, the DMDAMAV512 offers efficient switching capabilities up to 15,000 cycles per hour while maintaining leak-proof operation under maximum pressure conditions.

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.
