The Sun Hydraulics DMDAMPN648 (DMDAMPN648) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control mechanism. Engineered for robust functionality, this valve operates without the need for minimum hydraulic pressure, making it suitable for a wide range of applications. It exhibits a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity up to 12 gpm (45 L/min), which ensures efficient handling of medium to high-pressure systems. The model is designed with durability in mind; the solenoid tube assembly is fatigue rated for intense service conditions. Its switching frequency can reach up to 15,000 cycles per hour, coupled with a typical response time of 50 ms, which promotes rapid system responses essential in dynamic engineering environments. The manual override feature included in models equipped with D or L control utilizes a detent mechanism intended for temporary actuation only and supports around 7,000 mechanical life cycles. Additionally, the DMDAMPN648 uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of the valve allows fluid contact with the armature which helps in heat management but requires consideration regarding fluid type due to potential breakdown from prolonged exposure to high temperatures. This valve also incorporates Sun Hydraulics' floating style construction which minimizes internal part binding caused by installation torque or cavity/cartridge machining variations. Overall, the Sun Hydraulics DMDAMPN648 offers a reliable solution for directing flow within hydraulic systems where performance and durability are critical.

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.
