The Sun Hydraulics DMDAMPN848 (DMDAMPN848) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for demanding applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially suitable for pilot control operations where capacity is less critical. With a flow capacity of 12 gpm (45 L/min), the DMDAMPN848 operates efficiently with no minimum hydraulic pressure requirement for activation, making it versatile for various hydraulic systems. It incorporates a wet armature design, ensuring that the working fluid surrounds the armature which helps in heat management during prolonged coil energization but requires careful selection of fluids to prevent breakdown and varnish formation. The valve also supports interchangeable coils with other Sun Series 1 solenoid products, offering flexibility in maintenance and replacement processes. The manual override feature in models equipped with D or L control is designed for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. Furthermore, this model uses EPDM seals suitable for phosphate ester fluids but incompatible with petroleum-based fluids which could damage the seals. Sun Hydraulics has integrated its floating style construction into this model to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This attention to construction detail ensures reliable operation and longevity of the valve under varied installation conditions.

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.
