The Sun Hydraulics DMDATRV948 (DMDATRV948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve features a unique construction that includes a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar). 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 useful in pilot control applications where capacity is less critical. The DMDATRV948 operates without the need for minimum hydraulic pressure, making it versatile for various system conditions. It includes manual override options with detent mechanisms designed for temporary actuation; these models are equipped with either D or L control options. The mechanical life expectancy of the manual control assembly is approximately 7,000 cycles. It is important to note that cartridges fitted with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based substances can damage these seals. This valve employs a wet armature design allowing the working fluid to surround the armature which can be relevant when considering the type of fluid used due to potential breakdowns from prolonged heat exposure. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and upgrades. Additionally, its design incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by installation or machining variances. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and a switching frequency capable of accommodating up to 15,000 cycles per hour. This model's robust design and advanced features make it suitable for demanding applications requiring precise hydraulic flow 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.
