The Sun Hydraulics DMDATPN812 (DMDATPN812) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is characterized by its robust construction and high-pressure rating, capable of handling up to 5000 psi (350 bar). The DMDATPN812 features closed transitions between spool positions B and R, optimizing performance by enhancing response times and consistency, particularly suitable for applications where rapid actuation is critical. This valve operates without requiring a minimum hydraulic pressure, making it versatile for various low-pressure applications. It includes a manual override feature with a detent mechanism designed for temporary operation, supported by a mechanical life expectancy of around 7,000 cycles. The DMDATPN812 is compatible with EPDM seals specifically for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can degrade the seals. Equipped with a wet armature design, the valve\u2019s armature is immersed in the working fluid which helps manage heat dissipation from the coil but requires consideration of fluid type to prevent breakdown and varnish formation. It offers interchangeable coils that can be mounted in either direction on the tube and shares compatibility with other Sun Series 1 solenoid products. Additionally, Sun Hydraulics incorporates their floating style construction in this model to minimize internal parts binding caused by installation torque or cavity/cartridge machining variations. With specifications like a flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 3000 psi being only 5 in\u00b3/min (80 cc/min at 210 bar), the DMDATPN812 is engineered for efficient and reliable performance in demanding hydraulic setups.

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.
