The Sun Hydraulics DMDAMPN (DMDAMPN) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a robust design with spools B and R maintaining a closed transition between positions, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDAMPN incorporates a wet armature design, where the working fluid envelops the armature, potentially affecting fluid integrity under prolonged energization. It is essential to note that cartridges with EPDM seals are suitable for phosphate ester fluids but should not be exposed to petroleum-based substances which could damage the seals. This valve model also offers flexibility in manual control with the D or L control options featuring a detent mechanism designed primarily for temporary actuation, supporting around 7,000 mechanical life cycles. Additionally, this valve model benefits from Sun Hydraulics' floating style construction which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. The interchangeable coils compatible with other Sun Series 1 solenoid products add to the versatility of this device, allowing mounting on the tube in either direction to suit various installation requirements. The typical response time for this valve is around 50 ms, and it supports up to 15,000 switching cycles per hour, making it an efficient choice for dynamic systems requiring frequent actuations.

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.
