The Sun Hydraulics DMDAMPV948 (DMDAMPV948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in complex systems. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve's spools B and R are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times especially when used as pilot controls. The DMDAMPV948 operates without the need for minimum hydraulic pressure, facilitating versatile usage across various hydraulic systems. It includes an option for manual override through the D or L control mechanisms, although these are intended primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Special attention is required when selecting seals; models equipped with EPDM seals are compatible only with phosphate ester fluids and must avoid exposure to petroleum-based substances to prevent damage. This model incorporates Sun Hydraulics\u2019 floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Additionally, the wet armature design where the working fluid surrounds the armature can impact fluid integrity if coils remain energized over extended periods. The valve supports a flow capacity of up to 12 gpm (45 L/min) and offers rapid response times typically around 50 ms. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility and maintenance ease of this valve, allowing for straightforward replacements or upgrades within the system setup. This makes the DMDAMPV948 an adaptable solution for dynamic hydraulic needs while maintaining reliability and efficiency in operation.

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.
