The Sun Hydraulics DMDALBV512 (DMDALBV512) is a solenoid-operated 3-way, 2-position cartridge valve, designed as a direct-acting, balanced spool directional valve. This model is distinguished by its robust construction, including a fatigue-rated solenoid tube assembly suitable for 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R to enhance performance limits at the cost of reduced capacity, making it ideal for pilot control applications where capacity is less critical. This approach ensures faster and more consistent response times. The DMDALBV512 operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. It also includes manual override options with detent mechanisms (in models equipped with the D or L control), designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. It is important to note that cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; exposure to petroleum-based substances can damage these seals. This valve's design incorporates a wet armature setup where the working fluid surrounds the armature which could be susceptible to heat during prolonged energization\u2014potentially leading to breakdowns in certain fluid types like water-glycol mixtures. Additionally, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction of this valve utilizes Sun\u2019s floating style design to minimize internal parts binding from excessive installation torque or cavity/cartridge machining variations. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the DMDALBV512 is engineered for high efficiency and reliability in demanding applications.

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.
