The Sun Hydraulics DMDAMNN948 (DMDAMNN948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures robust performance and reliability with its fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. The valve features closed transitions between spools B and R, optimizing performance by providing faster and more consistent response times when used as pilot controls. Engineered for versatility, the DMDAMNN948 requires no minimum hydraulic pressure to operate, making it suitable for a wide range of applications. It includes options for manual override through the D or L control detent mechanism, specifically designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. This model is compatible with EPDM seals intended for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. The wet armature design of the valve allows the working fluid to surround the armature which helps in heat dissipation but could lead to breakdowns in certain fluids over prolonged energization periods. Moreover, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction for added installation flexibility. Additional attributes include a flow capacity of 12 gpm (45 L/min), a swift response time typically around 50 ms, and minimal maximum valve leakage at high pressures. The manual override features require low force, facilitating ease of operation under pressure. The construction incorporates Sun's floating style to minimize internal parts binding caused by installation torque or machining variations. This makes the DMDAMNN948 an ideal choice for advanced hydraulic systems requiring reliable and efficient 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.
