The Sun Hydraulics DMDATPV512 (DMDATPV512) is a solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring robust performance even under high-pressure conditions. The valve operates with no minimum hydraulic pressure required, allowing for versatile implementation across various hydraulic systems. Key specifications include a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms. It boasts a maximum operating pressure limit of 5000 psi (350 bar), with switching frequencies reaching up to 15,000 cycles per hour. The manual override requires minimal force (5 lbs at 1000 psi for Port 1), demonstrating ease of operation during manual interventions. Notably, the DMDATPV512 employs EPDM seals when configured for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. Additionally, its wet armature design allows the working fluid to surround the armature which could be a consideration during extended periods of coil energization due to potential thermal degradation of certain fluids. This model also features interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun's floating style construction which minimizes internal parts binding from excessive installation torque or cavity/cartridge machining variations. The compact size (.60 lb weight and .75 in solenoid tube diameter) and durable build enhance its applicability in tight spaces and demanding environments where reliable directional control is essential.

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.
