The Sun Hydraulics DMDATAN948 (DMDATAN948) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. Designed as a direct-acting, balanced spool directional valve, it features a fatigue-rated solenoid tube assembly suitable for high-pressure service up to 5000 psi (350 bar). The valve's construction includes spools B and R which are closed during transition between positions, enhancing performance by providing faster and more consistent response times especially in pilot control applications where flow capacity is less critical. This model benefits from a direct actuation mechanism that operates without the need for minimum hydraulic pressure, making it versatile across various applications. It includes options for manual override through the D or L control detent mechanism designed primarily for temporary activation with a mechanical life expectancy of about 7,000 cycles. Additionally, the valve is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. The DMDATAN948 utilizes a wet armature design wherein the working fluid envelops the armature mitigating the heat generated by the coil\u2014important to consider if the coil remains energized over extended periods. This model also supports interchangeable coils with other Sun Series 1 solenoid products and features Sun's floating style construction that minimizes internal part binding due to installation stresses or component machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this cartridge is an effective solution for dynamic hydraulic system needs.

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.
