The Sun Hydraulics DMDAMPN814 (DMDAMPN814) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is notable for its robust construction and reliable performance in demanding applications. The valve features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar), making it suitable for high-pressure systems. It incorporates B and R spools that are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times, especially when used as pilot controls. This model operates without requiring a minimum hydraulic pressure, offering versatility in various hydraulic circuits. Additionally, the valve includes manual override options with a detent mechanism designed primarily for temporary actuation. The DMDAMPN814 is engineered with durability in mind, having a mechanical life expectancy of approximately 7,000 cycles for models equipped with D or L control. The cartridge utilizes EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based fluids to prevent seal damage. Its wet armature design allows the working fluid to surround the armature which can impact fluid integrity under prolonged energization conditions. The valve's interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Furthermore, the DMDAMPN814 benefits from Sun's floating style construction which minimizes internal part binding due to installation torque or variations in cavity/cartridge machining. This model has a maximum capacity of 12 gpm (45 L/min) and offers rapid response times typically around 50 ms. It also supports switching frequencies up to 15,000 cycles per hour and ensures minimal leakage at high pressures. Designed for easy installation and maintenance, this valve is an efficient solution for sophisticated hydraulic systems requiring reliable directional control.

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.
