The Sun Hydraulics DMDAMPN812 (DMDAMPN812) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate seamlessly without minimum hydraulic pressure. It features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability under demanding conditions. The valve's spools, B and R, remain closed during the transition between positions to enhance performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. This model incorporates a wet armature design where the working fluid surrounds the armature, which could be significant in applications where the coil is energized for extended periods, as it may affect fluid integrity due to heat exposure. The valve supports a maximum flow capacity of 12 gpm (45 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). Its quick response time of approximately 50 ms and compatibility with EPDM seals make it ideal for systems using phosphate ester fluids. Additionally, the DMDAMPN812 features interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also benefits from Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With a mechanical life expectancy of around 7,000 cycles for models equipped with manual control assemblies (D, L, T), this valve is built to provide reliable service over its operational lifespan.

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.
