The Sun Hydraulics DMDADBV612 (DMDADBV612) 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 engineered to operate without minimum hydraulic pressure, enhancing its versatility in various applications. It features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for demanding environments. The valve's design includes closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially beneficial when used as pilot controls. The manual override option comes with a detent mechanism intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. This model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of the valve means that the working fluid surrounds the armature which could be susceptible to heat during prolonged coil energization \u2014 an important consideration depending on the hydraulic fluid used. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility of this model, allowing for easy maintenance and replacement. Furthermore, it incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time of 50 ms. The valve also supports a high switching frequency up to 15,000 cycles/hr. Designed for efficient performance and reliability in hydraulic systems, the DMDADBV612 is an excellent choice for applications requiring precise control and durability.

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.
