The Sun Hydraulics DMDATBV912N (DMDATBV912N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to efficiently control the direction of fluid flow in a hydraulic system. The valve features a unique closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. Constructed to handle demanding conditions, the DMDATBV912N operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It boasts a fatigue rating for up to 5000 psi (350 bar), ensuring reliability and durability in high-pressure environments. The manual override option included in models with D or L control uses a detent mechanism intended for temporary actuation, with an expected mechanical life of around 7,000 cycles. This model is compatible with EPDM seals specifically designed for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The valve's wet armature design allows the working fluid to surround the armature which helps manage heat during prolonged coil energization but requires consideration regarding fluid compatibility. Additionally, the DMDATBV912N incorporates interchangeable coils that are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Its floating style construction minimizes internal parts binding which could occur due to excessive installation torque or variations in cavity/cartridge machining. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms, this valve is an excellent choice for sophisticated hydraulic systems requiring precise control and robust performance.

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.
