The Sun Hydraulics DMDAMBV512 (DMDAMBV512) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is well-suited for use in systems requiring reliable control of fluid direction. Its solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring durability and long service life even under demanding conditions. The DMDAMBV512 features closed transitions between positions B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. For manual override operations, it includes a detent mechanism designed to support temporary actuation with a mechanical life expectancy of around 7,000 cycles. Equipped to handle different fluid types, the DMDAMBV512 model configured with EPDM seals is specifically designed for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids which could cause damage. Additionally, the valve's wet armature design allows the working fluid to surround the armature which could be sensitive to prolonged heat exposure from the coil. This valve is compatible with other Sun Series 1 solenoid products concerning coil interchangeability and can be mounted in either direction on the tube. It also incorporates Sun\u2019s floating style construction that minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The DMDAMBV512 supports up to 12 gpm (45 L/min) flow capacity and allows a maximum operating pressure of 5000 psi (350 bar), making it a reliable choice for high-pressure applications requiring precise control.

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.
