The Sun Hydraulics DMDATRV812N (DMDATRV812N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control in hydraulic systems. The valve operates efficiently with a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), making it suitable for various demanding applications. It features a quick response time of approximately 50 ms and is capable of handling up to 15000 switching cycles per hour. This model incorporates a wet armature design which allows the working fluid to surround the armature, aiding in heat management when the coil is energized for extended periods. However, this design requires careful consideration of the fluid type used; specifically, EPDM seals in the cartridges are intended for phosphate ester fluids and should not be exposed to petroleum-based products. The DMDATRV812N also boasts interchangeable coils with other Sun Series 1 solenoid products, enhancing versatility and ease of maintenance. The manual override mechanism included in models with D or L control is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, this valve features Sun\u2019s floating style construction, minimizing internal parts binding due to installation torque or cavity/cartridge machining variations. For environments requiring robust control and reliability in hydraulic directional operations, the Sun Hydraulics DMDATRV812N offers an effective solution with its high-performance specifications and flexible design features.

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.
